Abstract

A wire-wound inductor includes a substantially square-flanged core member and a case core member. The substantially square-flanged core member includes an upper substantially square flange and a lower substantially square flange. The substantially square-flanged core member, around which a coil is wound, is inserted into the case core member, and the upper flange of the substantially square-flanged core member is fitted in an opening of the case core member. A planar corner abutment surface is provided at each of the four corners of the inner surface of the substantially square opening, and the corners of the upper flange abut the respective planar corner abutment surfaces.
