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

FIG. 4 is an oblique perspective view of the inductor pertaining to Comparative Example 2. As shown in FIG. 4, an inductor 600 in Comparative Example 2 has its coil conductor 36 electrically connected to the external electrodes 50, via the lead conductor parts 38, at positions on the end faces 16, closer to the bottom face 14, of the element body part 10. The lead conductor parts 38 are each connected to an external electrode 50 over a rectangular shape. The remainder of the constitution is the same as in Example 1 and therefore not explained.

FIG. 5 is an oblique perspective view of the inductor pertaining to Comparative Example 3. As shown in FIG. 5, an inductor 700 in Comparative Example 3 has its coil conductor 36 electrically connected to the external electrodes 50, via the lead conductor parts 38, at the top face 12 of the element body part 10; however, the coil conductor 36 is wound (circling) in the direction opposite to the direction in Example 1. In other words, the coil conductor 36 extends from the ends 40, 42, by means of the first conductors 32, along the end faces 16 of the element body part 10. This means that the coil conductor 36 does not extend from the ends 40, 42 along the top face 12 of the element body part 10. The remainder of the constitution is the same as in Example 1 and therefore not explained.
