Abstract
A coil component includes a body and an external electrode. The body includes a coil conductor formed by winding a substantially rectangular wire covered with an insulating film, and a magnetic-body section containing a magnetic-body particle and a resin. The external electrode is electrically connected to an exposed surface of an extended portion of the coil conductor and is disposed at a surface of the body, the exposed surface being exposed at the surface of the body. The body includes first and second principal surfaces that face each other. At the wire, an average thickness of a portion of the insulating film that covers a first surface facing the first principal surface and extending in a direction orthogonal to a winding axis of the coil conductor is larger than average thicknesses of portions of the insulating film that cover other surfaces, orthogonal to the first surface, of the wire.
