PROBLEM TO BE SOLVED: To provide a small-sized inverter transformer in which a fixing area to mounting substrate is reduced. SOLUTION: The inverter transformer is provided with a closed magnetic circuit core 24, a primary winding 25 and a secondary winding 26 which are wound around outer leg parts 22, and terminals 27 with which the primary winding 25 and the secondary winding 26 are connected. In the core 24, a plurality of the outer leg parts 22 are continuously connected with facing flat plate type rear leg parts 21, and a closed magnetic circuit is formed by continuously connecting a middle leg part 23. Two outer leg parts 22 around which the secondary winding 26 is wound is installed. One outer leg part 22 around which the primary winding 25 is wound is installed. The mutual outer leg parts 22 are arranged facing with each other. The middle leg part 23 is arranged between the mutual outer leg parts 22, facing them. |
