Abstract
A coil component includes an air-core coil embedded in a magnetic body constituted by resin and metal magnetic grains. Both ends of the coil are exposed on the surface of the magnetic body, and the side on which both ends are exposed is polished and etched to form terminal electrodes. To be specific, an underlying layer of metal material is formed across the surface of the magnetic body and the ends by means of sputtering, and then a cover layer is formed. Where the magnetic body contacts the underlying layer, the areas where the underlying layer is in contact with the resin ensure insulation, while the contact between the underlying layer and the exposed parts of the metal magnetic grains ensures adhesion, thus increasing the adhesion strength with respect to the terminal electrodes.
