ABSTRACT:
A common-mode choke coil includes a core having flanges disposed at both ends and a winding section arranged between the flanges. Electrodes are disposed in the flanges, while two pieces of wire are wound around the winding section and ends of the pieces of wire are connected to the electrodes. A ferrite plate with a relative magnetic permeability that is smaller than that of the core is attached on the upper surface of the flanges with an adhesive so as to cover the wire.
