As shown in Figure 6, the 2nd fixed part 162 has the 2nd upper surface portion 162a relative with the installation surface 142a of outer cored 140, with 144 relative the 2nd lower face 162b below the core of outer cored 140 and be connected the 2nd upper surface portion 162a and the 2nd lower face 162b and the 2nd side surface part 162c relative with core outer peripheral face 146.Further, at the 2nd upper surface portion 162a and the 2nd lower face 162b, different from the 1st execution mode, do not form the protuberance being sticked in outer cored 140.2nd connecting portion 166 there is the 2nd circumferential direction portion 166a that extends in the circumferential direction from the 2nd fixed part 162 along core outer peripheral face 146 and from the 2nd circumferential direction portion 166a to the 2nd wiring bottom the 2nd axial part 166b that extends in the vertical direction of 164a.As shown in Figure 7,2nd wire connecting portion 164 has 164a bottom the 2nd wiring relative with the bearing-surface 142b of outer cored 140, gives prominence to from 164a upward direction bottom the 2nd wiring and winding end portion 130b be sandwiched in a pair the 2nd protrusion tab portion 164b therebetween, 164c and be connected to 164a bottom the 2nd wiring and clip the 2nd press section 164d of winding end portion 130b between 164a in the vertical direction bottom the 2nd wiring.Have again, although the configuration relation of the 1st portion of terminal 150 its 1st fixed part 152 comprised, the 1st wire connecting portion 154 and the 1st connecting portion 156 is different from the 2nd portion of terminal 160, but the shape of the 1st fixed part 152, the 1st wire connecting portion 154 and the 1st connecting portion 156 self is roughly the same with the 2nd portion of terminal 160, thus omits their explanation.
In the coil component 100 involved by the 2nd execution mode, 1st portion of terminal 150 and the 2nd portion of terminal 160 are not the relations of Mirror Symmetry, and from the flange part 24 to the interval of 164a bottom the 2nd wiring than inner core 20 bottom the 1st wiring, the diameter of 26 is large, but the 1st wire connecting portion 154 and the 2nd wire connecting portion 164 in mode winding end portion 130a, 130b can extracted out point-blank from core portion 22 with appropriate angle configurations.In addition, the coil component 100 involved by the 2nd execution mode also plays the effect same with the coil component 10 involved by the 1st execution mode.
Further, an above-mentioned execution mode only example comprising of embodiments of the present invention, as long as the technical problem in invention can be solved, just various change can be increased to execution mode.Such as, inner core 20 is the so-called drum type cores at both ends with flange part, but be not limited to the inner core shown in Fig. 2 etc. as the inner core 20 that coil component 10 uses, the cross sectional shape of core portion 22, upper flange part 24 and lower flange 26 also can be ellipse or polygon etc.In addition, the upper flange part 24 of inner core 20 can be consistent with the diameter of lower flange 26, can also be different.As shown in execution mode, by making the diameter L2 of upper flange part 24 larger than the diameter L3 of lower flange 26, thus gap can be formed effectively between lower flange outer peripheral face 26a and in-core side face 48.In addition, also upper flange part outer peripheral face 24a and lower flange outer peripheral face 26a can be engaged in the in-core side face 48 of outer cored 40, also any one in the middle of only upper flange part outer peripheral face 24a and lower flange outer peripheral face 26a can be engaged relative to in-core side face 48.
