Abstract
A coil component is capable of suppressing occurrence of peeling at an interface between a coil conductor and resin in a magnetic portion due to heating during mounting. The coil component includes an element body that includes a coil conductor formed by winding a conductive wire coated with an insulating film, and a magnetic portion that contains metal magnetic particles and resin, and external electrodes that are electrically connected to exposed surfaces of extended portions of the coil conductor exposed on a surface of the element body, and are arranged on the surface of the element body. The metal magnetic particles are arranged in recesses formed in a surface of the conductive wire in the extended portions of the coil conductor.
