6. The connector as claimed in claim 4 , wherein substrate contact parts of the multiple pairs of signal contacts, arranged in one of the two arrays, face substrate contact parts of the multiple pairs of signal contacts arranged in the other one of the two arrays, all the substrate contact parts extending in the same direction.

7. The connector as claimed in claim 4 , wherein a pair of signal contacts arranged in one of the two arrays and a pair of signal contacts arranged in the other one of the two arrays exist between each two neighboring ground contacts.

8. The connector as claimed in claim 4 , wherein a pair of signal contacts arranged in one of the two arrays and a pair of signal contacts arranged in the other array that faces the one of the two arrays via an insulating member exist between each two neighboring ground contacts.

9. The connector as claimed in claim 4 , wherein a pair of signal contacts arranged in one of the two arrays and a pair of signal contacts arranged in the other array that faces the one of the two arrays via a space exist between each two neighboring ground contacts.

10. The connector as claimed in claim 4 , wherein each of the ground contacts is provided across both two arrays, and has top ends facing each other.

11. The connector as claimed in claim 4 , wherein parts of the signal contacts to be connected to a mating connector extend in a direction perpendicular to parts of the signal contacts to be connected to a substrate.

12. The connector as claimed in claim 4 , wherein parts of the signal contacts to be connected to a mating connector extend in the opposite direction from parts of the signal contacts to be connected to a substrate.

13. The connector as claimed in claim 4 , wherein the signal contacts arranged in the two arrays are aligned at intervals in the longitudinal direction of the connector.

14. The connector as claimed in claim 4 , further comprising other signal contacts that are provided in each array,

the other signal contacts in each array are arranged at intervals, without the ground contacts being interposed among the other signal contacts.
