In addition, in the present embodiment, the composition identical with the composition of the 1st above-mentioned embodiment, adopts the numeral same with this composition, and letter attached in illustrating on the other hand is not " A " but " C ".
Fig. 8 is the exploded perspective view of the composition of the coil component 10C representing the present embodiment.Fig. 9 is the stereogram of the composition representing magnetic core array 20C.As can be seen from figures 8 and 9, in the coil component 10C of the present embodiment, the shape forming the magnetic core component 21C of magnetic core array 20C is different.That is, as shown in Figure 9, each magnetic core component 21C, compare with magnetic core component 21A, the 21B shown in Fig. 3 with Fig. 6, cancave embedded part 25C, 26C are positioned at the end side of Y-direction.
Further, in attachment 23C, the position of the end face 23C1 near mutual apical grafting does not arrange cancave embedded part 25C, 26C.In addition, in composition as can be seen from figures 8 and 9, disturb to prevent from producing between hook fastener 27C, cancave embedded part 26C is arranged on the diverse location of X-direction.
That is, to be positioned at the design of bottom side (Z2 side) inadvisable for the hook portion 53C of adsorption cover 50C.Its reason is, the lower fastener 42C of terminal component 40C is necessary to divide with the wire connecting portion of mount substrates to contact.Thus, lower fastener 42C must be positioned at bottom side (Z2 side).In addition, time adsorption cover 50C is arranged on magnetic core array 20C, need not produce interference between terminal component 40C and adsorption cover 50C.
So in the present embodiment, as can be seen from figures 8 and 9, cancave embedded part 26C and hook fastener 27C is arranged on the diverse location of X-direction.In addition, in order to allow between terminal component 40C mutually away from, preferred terminal component 40C is positioned at the side, corner of magnetic core array 20C.Thus, cancave embedded part 26C is positioned at the end side of X-direction more than hook fastener 27C.
In addition, in composition as shown in Figure 8, the distance between a pair hook fastener 27C is shorter than the distance between a pair cancave embedded part 26C.Thus, the size of the X-direction of adsorption cover 50C can be set to very little.Therefore, in the present embodiment, adsorption cover 50C is in the entirety not hiding magnetic core array 20C, and a part of magnetic core array 20C is in the composition highlighted.But, this also can not be adopted to form, that is, the flat part 51C of adsorption cover 50C can be allowed to hide the entirety of magnetic core array 20C.
In addition, as magnetic core component 21C, composition as shown in Figure 10 also can be used.Figure 10 is the figure of the variation of the magnetic core component 21C represented in the 3rd embodiment, also represents the half-sectional view under the state cutting off wireline reel portion 22C.In magnetic core component 21C, same with the magnetic core component 21A shown in Fig. 4, periphery wall 22C1 and internal perisporium 22C2 is configured to the curved shape of arc-shaped etc.Thus, coil 30C, relative to periphery wall 22C1 and to internal perisporium 22C2, can be very close to each other, or the state that gap is very little.In addition, because the angle in bight that the wire 31C in wireline reel portion 22C contacts becomes gentle, so the risk that the wire 31C that also can reduce coil 30C breaks.
In the coil component 10C as above formed, cancave embedded part 25C, 26C are positioned at the end side of the Y-direction of magnetic core array 20C.Thus, compare with the composition shown in Fig. 2 with Fig. 6, the distance in the Y-direction of terminal component 40C can be zoomed out.Thus, the bad problem producing electric discharge etc. between pair of terminal parts 40C can just be prevented.In addition, because the distance between pair of terminal parts 40C can be zoomed out, so coil component 10C can be made further miniaturized.
