Abstract

A coil component includes a core and a coil that is wound around the core. The coil includes a plurality of pin members that are joined together.

Claims

1. A coil component comprising:

a core; and

a coil that is wound around the core,

wherein the coil includes a plurality of pin members that are joined together.

2. The coil component according to claim 1,

wherein the plurality of pin members are joined together by using a joining material.

3. The coil component according to claim 1,

wherein at least some of the pin members that are adjacent to each other in an axial direction of the coil are isolated from each other with a space therebetween.

4. The coil component according to claim 1,

wherein at least some of the pin members that are adjacent to each other in an axial direction of the coil are isolated from each other with a dielectric material therebetween.

5. The coil component according to claim 1,

wherein the plurality of pin members include a plurality of first pin members and a plurality of second pin members, and

wherein the first pin members and the second pin members have different shapes and are alternately joined together.

6. The coil component according to claim 5,

wherein the first pin members are bent pins that are substantially U-shaped and the second pin members are straight pins that extend substantially straight.

7. The coil component according to claim 1,

wherein the core is annular, and

wherein the coil component further comprises a holding member that holds the coil, the holding member being disposed between at least one of two end surfaces of the core in an axial direction of the core and a part of the coil that faces the at least one of the two end surfaces of the core.

8. The coil component according to claim 7,

wherein the holding member is disposed between each of the two end surfaces of the core in the axial direction of the core and a part of the coil that faces a corresponding one of the two end surfaces of the core.

9. The coil component according to claim 7,

wherein the holding member is an insulating substrate.

10. The coil component according to claim 9, further comprising:

an insulating member that is disposed on each of an inner peripheral surface and an outer peripheral surface of the core.

11. The coil component according to claim 10,

wherein the insulating member is an insulating tape.

12. A coil component comprising:

an annular core;

a coil that is wound around the core; and

a holding member that holds the coil, the holding member being disposed between at least one of two end surfaces of the core in an axial direction of the core and a part of the coil that faces the at least one of the two end surfaces of the core.

13. The coil component according to claim 12,

wherein the holding member is disposed between each of the two end surfaces of the core in the axial direction of the core and a part of the coil that faces a corresponding one of the two end surfaces of the core.

14. The coil component according to claim 12,

wherein the holding member is an insulating substrate.

15. The coil component according to claim 14, further comprising:

an insulating member that is disposed on each of an inner peripheral surface and an outer peripheral surface of the core.

16. The coil component according to claim 15,

wherein the insulating member is an insulating tape.

17. The coil component according to claim 12,

wherein the coil includes a plurality of pin members that are joined together.

18. A method of making a coil component, the method comprising:

attaching a plurality of first pin members to a core; and

forming a coil, which is wound around the core, from the plurality of first pin members and a plurality of second pin members by joining the second pin members to the first pin members so that the first pin members and the second pin members are alternately arranged.
