PURPOSE:To reduce eddy current loss of a magnetic core at a high-frequency region by a method wherein a fine wire consisting of a soft magnetic metal having 20 oersted or less of coercive force, and moreover having 0.01mm.<2> or less of the sectional area is wound round. CONSTITUTION:The fine wire 1 of a soft magnetic metal is wound round in a loop type to form a toroidal type magnetic core 2. An exciting winding 3 is wound around the magnetic core 2 by the desired number of turns, and moreover an output winding 4 is wound around by the desired number of turns as occasion demands. The fine wire 1 is made as to form a shape forming a magnetic path in bundled condition in relation to the exciting winding 3. As the manufacturing method of the fine wire of the soft magnetic metal, the desired soft magnetic metal is wrapt with a glass material, and after heated at the temperature of a melting point or more, wire drawing is performed to obtain the fine wire. |
