Inductor

1. An inductor comprising:

wherein the insulator includes first and second insulator portions adjacent to each other across the first opening, and a deviation between a thickness H 1 of the coil at the first insulator portion and a thickness H 2 of the coil at the second insulator portion, is equal to or less than 15% of an average thickness of the coil.

2. The inductor of claim 1 , wherein the second opening is filled with the insulator and the coil.

3. The inductor of claim 1 , wherein the thin film conductor layer is a single layer.

4. The inductor of claim 3 , wherein the thin film conductor layer contains one of copper, nickel, tin, gold, titanium, molybdenum, and silver.

5. The inductor of claim 1 , wherein the thin film conductor layer has a stacking structure composed of a plurality of layers.

6. The inductor of claim 5 , wherein the plurality of layers have the same line width as each other.

7. The inductor of claim 1 , wherein in the second opening, a portion of a lower surface of the coil pattern comes into direct contact with the support member.

8. The inductor of claim 1 , wherein an insulating layer is on an upper surface of the coil pattern.

9. The inductor of claim 8 , wherein the insulating layer extends inwardly from an innermost side surface of the insulator or extends outwardly from an outermost side surface of the insulator.

10. An inductor comprising:

a support member;

an insulator on the support member and including a first opening;

a coil in the first opening, between first and second insulator portions adjacent to each other across the first opening, with a lower surface having a first portion in direct contact with the support member; and

a thin film conductor layer on the support member, between the support member and a second portion of the lower surface of the coil, and including an end portion below the first insulator portion;

wherein the coil has an upper surface that inclines from a thickness H 1 at the first insulator portion to a thickness H 2 at the second insulator portion, where a deviation between H 1 and H 2 is equal to or less than 15% of an average thickness of the coil.

11. The inductor of claim 10 , further comprising:

a magnetic material encapsulating the support member, the insulator, the coil, and the thin film conductor layer; and

an insulating layer above the insulator and between the magnetic material and upper surfaces of the insulator and coil,

wherein the insulating layer is in direct contact with an innermost or outermost side surface of the coil.

12. The inductor of claim 11 , wherein at least a portion of an innermost or outermost side surface of the insulator is in direct contact with the magnetic material.

13. The inductor of claim 10 , wherein a width of the first and second insulator portions increases in a direction toward the support member.

14. An inductor comprising:

a support member;

an insulator on the support member and including a first opening;

a coil in the first opening, between first and second insulator portions adjacent to each other across the first opening, with a lower surface having a first portion in direct contact with the support member; and

a thin film conductor layer on the support member, between the support member and a second portion of the lower surface of the coil;

wherein the coil has an upper surface that inclines from a thickness H 1 at the first insulator portion to a thickness H 2 at the second insulator portion, where a deviation between H 1 and H 2 is equal to or less than 15% of an average thickness of the coil.

15. The inductor of claim 14 , further comprising:

a magnetic material encapsulating the support member, the insulator, the coil, and the thin film conductor layer; and

an insulating layer above the insulator and between the magnetic material and upper surfaces of the insulator and coil,

wherein the insulating layer is in direct contact with an innermost or outermost side surface of the coil.

16. The inductor of claim 15 , wherein at least a portion of an innermost or outermost side surface of the insulator is in direct contact with the magnetic material.

17. The inductor of claim 14 , wherein a width of the first and second insulator portions increases in a direction toward the support member.
