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.
