Abstract
A coil component includes a magnetic portion that includes metal particles and a resin material, a coil conductor embedded in the magnetic portion and having a core portion, and outer electrodes electrically connected to the coil conductor. The magnetic portion includes an outer coating and a magnetic base having a protrusion portion. The protrusion portion is inserted into the core portion. The filling factor of the metal particles in the magnetic base is higher than the filling factor of the metal particles in the outer coating.
