Abstract
In a coil component, the pressure resistance is improved by main surfaces and of a main body portion being covered with an insulating layer. The main body portion has a surface part, the resin ratio of the surface part is higher than the internal resin ratio, and insulation is enhanced at the surface part. As a result, the pressure resistance on the surface of the main body portion is further improved and the pressure resistance of the entire coil component is further improved.
