PURPOSE:To attain mechanization of production, mass-productivity attended with improvement of working efficiency and miniaturization by inserting a wire to the 1st and 2nd ferrites so as to attain balancing with excellent characteristic. CONSTITUTION:A metallic wire 17a is connected to an output terminal 14 via a hollow part of a ferrite 10 from an input terminal 12, a metallic wire 17b is connected to an output terminal 15 via a hollow part of a ferrite 11 from the input terminal 12, a metallic wire 18a is connected to the output terminal 15 via a hollow part of the ferrite 10 from an input terminal 13 and a metallic wire 18b is connected to an output terminal 10 via a hollow part of the ferrite 1 from the input terminal 13 respectively. Further, the metallic wires 17a, 17b, 18a, 18b are soldered to terminals 12-16. Thus, the metallic wires 17a, 17b, 18a, 18b have only to be inserted to the hollow part of the ferrites 10, 11 in this way, allowing to improve the manufacture efficiency.
