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(shuō)明書(shū)

Under the aforementioned constitution, a constitution may be adopted whereby one end of the two ends of the coil conductor is electrically connected to the external electrode at the second face of the element body part (referred to also as insulative body) via the lead conductor, while the other end is electrically connected to the external electrode at the first face of the element body part via the lead conductor, and the coil conductor extends from the one end to the second face of the element body part by way of the second conductors.

Under the aforementioned constitution, a constitution may be adopted whereby the lead conductors are each connected to an external electrode over a section of roughly circular shape.

Under the aforementioned constitution, a constitution may be adopted whereby the pair of external electrodes are provided on the pair of end faces of the element body part at least in areas opposing the multiple first conductors.

Under the aforementioned constitution, a constitution may be adopted whereby the marker part is provided on the second face of the element body part.

According to the present invention, the Q-value can be improved.

For purposes of summarizing aspects of the invention and the advantages achieved over the related art, certain objects and advantages of the invention are described in this disclosure. Of course, it is to be understood that not necessarily all such objects or advantages may be achieved in accordance with any particular embodiment of the invention.
