An object of the present disclosure is to provide a common mode choke coil with high impedance and small variation. A common mode choke coil includes magnetic core having winding core part and a pair of flange parts provided on opposite ends of winding core part, external electrodes formed on each of flange parts, a pair of windings wound on winding core part, with each of the ends being drawn out and joined to one of external electrodes, and magnetic plate joined to the pair of flange parts with adhesive. Magnetic plate has joining parts joined to flange parts and opposing part opposing winding core part, and surface roughness of joining parts is smaller than surface roughness of opposing part.

Common mode choke coil and manufacturing method therefor

A laminated ceramic component includes a ferrite magnetic layer and a glass ceramic layer made chiefly of borosilicate glass. The glass ceramic layer is laminated with the ferrite magnetic layer, and has an Ag inner conductor embedded inside. A microscopic region where aluminum and silver coexist is dispersed in the glass ceramic layer.
