摘要
A method of manufacturing a bead inductor includes the steps of forming a molded body of a resin material or a rubber material including a powdery magnetic substance with a conductor coil defined by a wound, coated metallic wire; cutting both ends of the molded body so as to expose the ends of the conductor coil; and attaching external terminals to the exposed ends of the conductor coil so that the external terminals are electrically connected to the conductor coil. The connection reliability between the conductor coil and the external terminals is greatly increased in the bead inductor manufactured by the method because convex portions protruding from the end surfaces of the molded body are provided on both ends of the conductor coil, which are exposed by cutting the molded body, so that the external terminals are attached and electrically connected to the convex portions.
