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.

Abstract: A coil component includes a magnetic body portion that includes metallic particles and a resin material, a coil conductor that is embedded in the magnetic body portion, and a first outer electrode and a second outer electrode each of which is electrically connected to the coil conductor. At least a portion of an outer layer of the magnetic body portion forms an electrically conductive layer that includes a second metallic material having a specific resistance lower than a specific resistance of a first metallic material forming the metallic particles. The electrically conductive layer includes a first electrically conductive layer that is electrically connected to the first outer electrode and a second electrically conductive layer that is electrically connected to the second outer electrode. The first electrically conductive layer and the second electrically conductive layer are electrically isolated from each other.
