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.
