wherein the mounting portions of contacts constituting at least two contact arrays adjacent to each other of the plurality of contact arrays extend in a same elongation direction, and

wherein contacts constituting each contact array of the at least two contact arrays are disposed in a position other than a position where those contacts completely coincide with contacts constituting another contact array of the at least two contact arrays in a direction perpendicular to the predetermined array direction.

2. The connector according to claim 1 ,

wherein the housing has an opening portion formed between the at least two contact arrays and extending in the predetermined array direction.

3. The connector according to claim 2 ,

wherein the mounting portions of contacts constituting one contact array of two contact arrays situated on opposite sides across the opening portion protrude in the opening portion.

4. The connector according to claim 1 ,

wherein the housing has a flat surface portion facing the mounting object, and

wherein the elongation direction of the mounting portions of the plurality of contacts is a direction along the flat surface portion of the housing and perpendicular to the predetermined array direction.

5. The connector according to claim 1 ,

wherein the plurality of contacts are aligned in the predetermined array direction at a predetermined array pitch in each of the plurality of contact arrays,

wherein each of the plurality of contacts has a predetermined contact width in the predetermined array direction,

wherein the at least two contact arrays comprise two adjacent contact arrays,

wherein the two adjacent contact arrays are arranged to be offset from each other by a half of the predetermined array pitch in the predetermined array direction, and

wherein the predetermined array pitch is larger than a double of the predetermined contact width.

6. The connector according to claim 1 ,

wherein the connector has a center line extending in the predetermined array direction, and

wherein the at least two contact arrays are disposed on each of opposite sides across the center line.

7. The connector according to claim 6 ,

wherein the mounting portions of contacts constituting the at least two contact arrays disposed on one of the opposite sides across the center line and the mounting portions of contacts constituting the at least two contact arrays disposed on the other of the opposite sides across the center line extend in opposite directions from each other.

8. The connector according to claim 1 ,

wherein the mounting portions of contacts constituting each contact array of the at least two contact arrays are disposed in a position where those mounting portions overlap the mounting portions of contacts constituting another contact array of the at least two contact arrays in the direction perpendicular to the predetermined array direction, and

wherein the contact portions of contacts constituting each contact array of the at least two contact arrays are disposed in a position where those contact portions do not overlap the contact portions of contacts constituting another contact array of the at least two contact arrays in the direction perpendicular to the predetermined array direction.

9. The connector according to claim 1 ,

wherein the contact portions of contacts constituting each contact array of the at least two contact arrays are disposed in a position where those contact portions overlap the contact portions of contacts constituting another contact array of the at least two contact arrays in the direction perpendicular to the predetermined array direction, and

wherein the mounting portions of contacts constituting each contact array of the at least two contact arrays are disposed in a position where those mounting portions do not overlap the mounting portions of contacts constituting another contact array of the at least two contact arrays in the direction perpendicular to the predetermined array direction.

10. The connector according to claim 1 ,

wherein each of the plurality of contacts has a portion to be retained between the mounting portion and the contact portion,

wherein the housing has a plurality of retaining portions corresponding to the portions to be retained of the plurality of contacts, and

wherein the portions to be retained of the plurality of contacts are press-fitted in and retained by the plurality of retaining portions of the housing, correspondingly.

11. The connector according to claim 1 ,

wherein the connector is a receptacle connector,

wherein the housing is a receptacle housing,

wherein the plurality of contacts are a plurality of receptacle contacts,

wherein each of the plurality of receptacle contacts has a spring contact that is elastically displaceable as the contact portion, and

wherein the counter connector is a plug connector that is to be fitted with the receptacle connector to thereby form a connector assembly together with the receptacle connector.

12. The connector according to claim 1 ,

wherein the connector is a plug connector,

wherein the housing is a plug housing,

wherein the plurality of contacts are a plurality of plug contacts,

wherein each of the plurality of plug contacts has a fixed contact that is secured in position as the contact portion, and

wherein the counter connector is a receptacle connector that is to be fitted with the plug connector to thereby form a connector assembly together with the plug connector.

13. A method of manufacturing a connector, comprising:

a step of retaining a plurality of contacts joined to a carrier via corresponding joint portions by a housing; and

a step of separating the carrier from the plurality of contacts retained by the housing,

wherein the plurality of contacts form a plurality of contact arrays that linearly extend in a predetermined array direction in parallel to each other,

wherein the joint portions joined to contacts constituting at least two contact arrays adjacent to each other of the plurality of contact arrays extend in a same elongation direction, and

wherein contacts constituting each contact array of the at least two contact arrays are disposed in a position other than a position where those contacts completely coincide with contacts constituting another contact array of the at least two contact arrays in a direction perpendicular to the predetermined array direction.
