ABSTRACT:
It is an object to decrease an occupied space in a printed board to carry out space saving and to reduce the size of a unit without sacrificing the performance of a transformer and increasing a cost.A transformer11is constituted by a bobbin13having at least a primary winding15and a secondary winding17wound therearound and a core21,and the side surface of the bobbin13is provided with a component holding section for holding high-voltage components such as a capacitor31and a diode33which constitute a voltage doubler rectifying circuit for rectifying a high voltage having a high frequency from the secondary winding15.
