Abstract

PURPOSE:To contrive accomplishment of low cost and miniaturization of the titled transfomer by a method wherein the insulating plate having the metal printed wiring on which a part of wiring and a circuit are formed, an insulating material with a through hole, and a toroidal core are formed in an integral structure. CONSTITUTION:A core 13 and an insulating material 14 are pinched between insulating plates 11 and 12, a metal printed wiring 5a is connected to a metal printed wiring 7a through the intermediary of a through hole 3a, and the wiring 7a is connected to a metal wiring 5b through the intermediary of a through hole 3b. Therefore, a single wiring is formed around a toroidal core 13 by the line constituted by wirings 5a, 7a and 5b. A multiple-wound wiring is formed by repeating the connection same as above a plurality of times. Through these procedures, a necessary primary winding can be obtained. The necessary secondary winding can be obtained by successively connecting metal printed wirings 6a-6c, 8a, 8b and through holes 4a-4c and the like. Also, when a circuit having a metal printed wiring is provided on insulating plates 11 and 12, and the transformer and said circuits are connected, connecting works are unnecessitated.
