PURPOSE:To miniaturize a core, by a method wherein a yoke part consists of a toroidal core, and a magnetic path for feedback consists of a part of the toroidal core. CONSTITUTION:Yoke parts 11 and 12 are located at opposite ends in the direction of the length of core legs 10u-10w, and the yoke parts 11 and 12 are formed of two oval toroidal cores 13, 13 positioned astride the lege 10u-10w. The toroidal cores 13, 13 are formed such that a linear part 13a and a semicircular end part 13a stretch from the core legs 10u-10w. A magnetic flux, which flows into the yoke parts 11 and 12 from the core legs 10u-10w, branches to two toroidal cores 13, 13, and feeds back after passing through a section stretching from the core legs 10u-10w. |
