摘要

In an embodiment, a coil component includes: an element body part 10; a coil conductor 36 constituted by first conductors 32 extending along the pair of end faces 16 and orthogonally to a bottom face 14, as well as second conductors 34 extending from one side, to the other side, of the pair of end faces and thereby connecting the multiple first conductors 32; lead conductor parts 38 electrically connected to two ends of the coil conductor, respectively; and a pair of external electrodes 50 electrically connected to the lead conductor parts; wherein at least one end of the coil conductor is electrically connected, via the lead conductor, to the external electrode at a top face 12 of the element body part; and the coil conductor extends from the at least the one end, using a second conductor, along and near the top face.

說明書

The two external electrodes 50, which are external terminals used for surface mounting, are provided in the Y-axis direction in a manner opposing each other. The external electrodes 50 are each provided in a manner extending from the bottom face 14, to the top face 12, via the end face 16, of the element body part 10, while also extending from the end face 16, to the side faces 18, of the element body part. In other words, the external electrodes 50 cover both Y-axis direction ends of the top face 12, bottom face 14, and the side faces 18, while covering the end faces 16, of the element body part 10. Also, the Y-axis direction length of the part of the external electrode 50 covering the side face 18 of the element body part 10 is shorter than the Y-axis direction length of the part of the external electrode 50 covering the top face 12 or bottom face 14 of the element body part 10.
