Abstract

A coil component includes a cover member containing an ultraviolet curable resin and a filler made of flat particles each having a major axis and a minor axis. The filler preferably contains talc particles. The particles of the filler contained in a portion of the cover member that covers a top surface of the flange are aligned to orient the major axes parallel or substantially parallel to the top surface. The filler contained in the portion of the cover member that covers the top surface has an area ratio of from 15.0% to 50.1% in a section of the cover member taken along a plane that passes through the central axis of a winding core portion and orthogonally intersects the top surface. The grain size of the particles of the filler in D50 is from 1 μm to 30 μm.
