ABSTRACT:
A leadless chip inductor having metallic terminal plates and a coil element fixed to the metallic terminal plates, the metallic terminal plates being partially enclosed, together with the coil element, by a resin molded cover, the portions of the metallic terminal plates exposed to the outside of the molded outer cover being bent along the edge of the molded cover so as to form terminals for connection to an external circuit. The mechanical and electrical connection between the metallic terminal plates and the lead lines led from the coil is achieved by brazing or welding the lead lines to the undersides of a narrow strip-shaped tabs which is projected from each metallic terminal plate. With this arrangement, the coil lead lines are securely connected to the metallic terminal plates.
