Abstract

One object is to improve the electrical insulation between a conducting wire and a dust core without forming an insulating layer such as a glass layer on the dust core. A coil component includes: a dust core including a first flange, a second flange, and a winding core, the first flange having an inside surface including a first surface and a second surface, the second flange being opposed to the inside surface of the first flange, the winding core extending in a core axis direction and connecting the first flange and the second flange, the dust core being formed of a plurality of metal magnetic particles bonded to each other via insulating material. The first surface may be less smooth than the second surface; and a conducting wire wound around the winding core so as to be in contact with the inside surface at the first surface.
