PURPOSE:To avoid the dimensional increase due to providing bobbin terminals by a method wherein the bobbin terminals on which ends of magnet wires are wound are formed into L-shape and protruded from the sides of the flanges of the bobbin. CONSTITUTION:A plurality of winding grooves 11b are formed in a bobbin 11 by a plurality of flanges 11a and a plurality of coils are provided by applying magnet wires to the bobbin 11 to constitute coil parts 10. L-shape bobbin terminals 13 are provided in such a manner that both of their ends are protruded from the flanges 11a and the ends of the respective coils 12 are connected to the protrusions 13a. The whole structure is covered with packaging resin 17 except the parts of external lead terminals 16 which are connected to external circuits. As the protrusions 13a of the terminals 13 are protruded from the sides of the flanges 11a of the bobbin 11, the total height of the bobbin 11 can be reduced and the dimensional increase due to providing terminals 13 can be avoided.
