Abstract
A coil component has a magnetic element body made of resin containing magnetic particles, a coil part embedded in the magnetic element body, conductor posts which are embedded in the magnetic element body and whose one ends are connected to the coil part and the other ends are exposed from the magnetic element body, an insulating layer interposed between the conductor posts and the magnetic element body, and other insulating layers interposed between the coil part and the magnetic element body. Since the insulating layer is interposed between the conductor posts and the magnetic element body, it is possible to ensure insulation performance between the conductor posts and the magnetic element body and to prevent the occurrence of peeling therebetween.
