    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.

Also, a capacitor electrode plate has a shape which is included in the shape of the coils when viewed from the axial direction thereof, in the vicinity of the connection point of the coils so as to be opposed to a portion of the coils, whereby the portion of the coils functions as a capacitor electrode.

    摘要： A radiant noise inhibiting assembly is constructed to inhibit a radiant noise in an electric cable connected to a digital type electronic device. The electric cable is covered by a substantially cylindrical magnetic structure which is constructed to act as a magnetic shield. A substantially cylindrical electrically conductive structure functioning as an electrostatic shield is disposed on the outside of the magnetic structure. Only a first end of the electrically conductive structure is connected to a ground of the electronic device, which first end is closer to the electronic device than a second end of the electrically conductive structure, which is not grounded. In this way, a portion of the radiant noise which is not completely absorbed by the substantially cylindrical magnetic structure is absorbed by the substantially cylindrical electrically conductive structure, thereby sufficiently inhibiting the radiant noise of the electric cable. Further, a substantially cylindrical case which is constructed to function as an electrically conductive structure and provide a function of an electrostatic shield is used. Thus, attaching such a substantially cylindrical case is the same as attaching an electrically conductive structure.

    摘要： A soft magnetic core is substantially cylindrical and a linear-shaped coil conductor is inserted through a hole in the central portion of the soft magnetic core. A hard magnetic material sheet has areas which are magnetized in a thickness direction thereof and the areas are arranged in strips so that a magnetization direction of adjacent strips is mutually opposite. The hard magnetic material is wound on the outside surface of the soft magnetic core and is fixed to the soft magnetic core. The direction of the areas formed as strips of the hard magnetic material is substantially perpendicular to the axial direction of the coil conductor.
