Shape.Thus, coil 30C, can be in very close to each other relative to periphery wall 22C1 and to internal perisporium 22C2, or gap very little
State.In addition, because the angle in the corner that the wire 31C in winding axle portion 22C is contacted becomes gentle, can also drop
The risk of low coil 30C wire 31C broken strings.
In the coil component 10C as above constituted, cancave embedded part 25C, 26C are located at the end of magnetic core array 20C Y-direction
Side.Thus, compared with the composition shown in Fig. 2 and Fig. 6, the distance in terminal component 40C Y-direction can be zoomed out.By
This, it is possible to prevent from producing between a pair of terminal part 40C the bad problem of electric discharge etc..In addition, because a pair of end can be zoomed out
The distance between subassembly 40C, it is possible to further minimize coil component 10C.
