[0048] (Structure of inductor parts)
[0049] figure 1 It is a top perspective view showing an inductor component according to an embodiment of the present invention. figure 2 is a bottom perspective view of the inductor part. image 3 It is a bottom perspective view showing the inside of an inductor component. Figure 4 It is an exploded perspective view of the inductor part.
[0050] Such as Figure 1 ~ Figure 4 As shown, the inductor component 1 has a case 2, an annular core 3 housed in the case 2, a first coil 41 and a second coil 42 wound around the core 3, and is mounted on the case 2 and connected to the case 2. The first to fourth electrode terminals 51 to 54 to which the first coil 41 and the second coil 42 are connected. The inductor component 1 is, for example, a common mode choke coil or the like.
[0051] The housing 2 has a bottom plate portion 21 and a box-shaped cover portion 22 covering the bottom plate portion 21 . The casing 2 is made of a material h...

[0121] Figure 7 It is a sectional view which shows 2nd Embodiment of a pin member. The second embodiment differs from the first embodiment in the shape of the end portion of the pin member. This different configuration will be described below. The other configurations are the same as those of the first embodiment, and are given the same reference numerals as those of the first embodiment, and description thereof will be omitted.
[0122] Such as Figure 7 As shown, the cross-sectional area of the portion of the second straight pin member 412A other than the weld portion 80 is equal to the cross-sectional area of the portion of the curved pin member 410 other than the weld portion 80 . The cross-sectional area of the curved pin member 410 refers to the cross-sectional area of the plane perpendicular to the extension direction (center line 410c) of the curved pin member 410, and the cross-sectional area of the second straight pin member 412A refers to the extension...

[0127] Figure 8AIt is a bottom view showing the third embodiment of the manufacturing method of the inductor component. The third embodiment differs from the first embodiment in the shape of the pin member. This different configuration will be described below. The other configurations are the same as those of the first embodiment, and are given the same reference numerals as those of the first embodiment, and description thereof will be omitted.
[0128] Such as Figure 8A As shown, in the adjacent second straight pin member 412B and curved pin member 410 , the end surface 412f of the end portion 412e of the second straight pin member 412B and the peripheral surface 410f of the end portion 410e of the curved pin member 410 are in contact with each other. At this time, the second linear pin member 412B and the curved pin member 410 are arranged on the core body 3 in a state where the width of the end portion 412e of the second linear pin member 412B decreases toward the end...
