Abstract
A common mode choke coil includes: a shaft part; a pair of flange parts formed on both ends of the shaft part to constitute a drum core together with the shaft part; a sheet core bonded, in a manner connecting the pair of flange parts across the shaft part, to the top faces of the flange parts facing away from the bottom faces of the flange parts to be mounted on a circuit board; a coil-shaped conductor constituted by sheathed conductive wires wound around the shaft part; and electrode terminals formed on the flange parts and electrically connected to the ends of the sheathed conductive wires; wherein the bonding surfaces of each of the flange parts and the sheet core have multiple contact areas where the flange part makes direct contact with the sheet core, as well as adhesive areas between the contact areas where an adhesive is disposed.
