Patent ID: 8438720

Claim:
A method of manufacturing a coil component comprising a drum-shaped core including a winding core portion and a pair of flange portions provided on both ends in an axial direction of the winding core portion, and a winding wound around the winding core portion, comprising: applying a mold releasing agent on at least one of opposed surfaces of the pair of flange portions; winding the winding around the winding core portion; applying a resin with magnetic powder formed of a thermosetting resin to a space on an outer periphery of the winding interposed between the pair of flange portions so as not to form a gap between the pair of flange portions; and thermally curing the resin with magnetic powder, so that the surface of the flange portion where the mold releasing agent is applied and the resin with magnetic powder are separated by a contraction of the resin with magnetic powder, so that a gap is formed.
