Abstract: Disclosed herein is an electronic component that includes: a base having a main surface; a passive element part formed on the main surface of the base; a magnetic resin layer formed on the main surface of the base so as to embed the passive element part therein, the magnetic resin layer having a surface extending substantially parallel to the main surface of the base; an insulating coat layer formed on a first area of the surface of the magnetic resin layer, the insulating coat layer having higher smoothness than the surface of the magnetic resin layer; and a terminal electrode formed on a second area of the surface of the magnetic resin layer and electrically connected to the passive element part.
