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.

First claim

What is claimed is:

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.
