<p>PROBLEM TO BE SOLVED: To ensure sufficient insulation between an outgoing line of one kind of winding formed at two or more positions of a bobbin and a wire of another kind of winding in a transformer. SOLUTION: A transformer includes two or more windings to be insulated electrically, and a bobbin 1 with a winding part 10 in which a magnetic core is partly inserted, is provided. The winding part 10 of the bobbin 1 has individual winding positions 15. One kind of winding from among two or more windings is turned on by at least two or more winding positions 15 at the winding part 10 in the bobbin 1. In this case, the bobbin 1 has an insulating wire storing hole 16 for storing an outgoing line of one kind of winding with a length between two or more winding positions 15, on which one kind of winding is turned, and a wire-passing groove 17 is joined with respect to the insulating storing hole 16 on a groove-bottom side.</p> |
