METHOD OF MANUFACTURING BEAD INDUCTOR AND THE BEAD INDUCTOR PRODUCED THEREBY

摘要

A manufacturing method of a bead inductor comprises the steps of forming a molded body of a resin or a rubber including a powdery magnetic substance with a conductor coil formed by winding a length of metallic wire coated thereon for insulation embedded therein; cutting the 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 as to be electrically connected. The connecting reliability between the conductor coil and the external terminals is increased in the bead inductor manufactured by the method. Convex portions protruding from the end surfaces of the molded body are formed on the both ends of the conductor coil, which are exposed by cutting the molded body, so that the external terminals are attached to be electrically connected to the convex portions.
