Abstract
One object is to provide a new type of coil element capable of reducing leakage magnetic flux. A coil element according to one embodiment of the present invention is provided with an insulator body made of a magnetic material and having a mounting surface and an upper surface opposed to said mounting surface, a coil conductor embedded in the insulator body, an external electrode electrically connected to the coil conductor, a shield layer provided on the upper surface of the insulator body and having a larger magnetic permeability than the insulator body, and a plating layer formed to cover the mounting surface of the external electrode and having a larger magnetic permeability than the insulator body. The plating layer is formed to be thicker than the shield layer.
