Abstract: Disclosed herein is a coil component that includes a coil pattern embedded in a resin body. The resin body includes a winding core area surrounded by the coil pattern and having a first surface and a substantially flat second surface different in the circumferential direction position from the first surface, and a first surrounding area covering the first surface of the winding core area. The coil pattern includes first sections extending along the first surface of the winding core area and second sections extending along the second surface of the winding core area. One ends of the first sections are connected respectively to their corresponding one ends of the second sections. The other ends of the first sections are connected respectively to their corresponding other ends of the second sections.

Abstract: Disclosed herein is a coil component that includes a coil pattern embedded in an element body and helically wound in a plurality of turns. The element body includes a support body having a cavity formed therein and a first insulating layer stacked on the support body so as to cover the cavity, thereby forming a hollow space inside the element body. The coil pattern includes a plurality of first sections formed along an inner wall of the cavity and a plurality of second sections formed on the first insulating layer. One ends of the plurality of first sections are connected respectively to their corresponding one ends of the plurality of second sections. The other ends of the plurality of first sections are connected respectively to their corresponding other ends of the plurality of second sections.

Abstract: There is provided a coil component including a coil portion that has at least one layer of planar coil including a coil-wound portion and an insulative layer which covers the periphery of the coil-wound portion, a covering portion that covers the coil portion and is constituted of a mixture including magnetic fillers and resin, and a conductor post that is penetratingly provided inside the covering portion and extends from the coil-wound portion to an upper surface of the covering portion along an axial direction of the planar coil. The conductor post has a post portion which extends from the coil-wound portion in the axial direction of the planar coil, and a lid portion which is exposed from the covering portion and extends from an end portion of the post portion on the upper surface side along a surface direction of the upper surface.
