摘要:
A coil component includes: a first magnetic resin layer in a lower area; a second magnetic resin layer in an inner diameter area surrounded by a coil pattern, an outer peripheral area that surrounds the coil pattern, and an upper area; and an insulating gap layer between the first and second magnetic resin layers. A part of the insulating gap layer positioned between the first magnetic resin layer and a part of the second magnetic resin layer positioned in the inner diameter area is curved in the axial direction. A magnetic substrate need not be used. The insulating gap layer is provided, allowing the insulating gap layer to function as a magnetic gap. The insulating gap layer is curved in the axial direction, so that a contact area between the insulating gap layer and the first and second magnetic resin layers are increased to enhance adhesion therebetween.
