Abstract:
A first leg (131) of a core (300) is disposed between a second leg (132) and a third leg (133). A first electroconductive member (121) includes a first winding (201) that is wound on the first leg (131), and a second winding (202) that is serially connected to the first winding (201) and that is wound on the second leg (132). A second electroconductive member (122) includes a third winding (203) that is wound on the first leg, and a fourth winding (204) that is serially connected to the third winding (203) and that is wound on the third leg (133). The first leg (131) is provided with a plurality of gaps, and includes a first core member made up of core pieces (306 through 308), and a plurality of first gap members (404 through 407) which are each configured of a nonmagnetic substance and respectively disposed in the plurality of gaps of the first core member.
