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 transformeris constituted by a bobbinhaving at least a primary windingand a secondary windingwound therearound and a coreand the side surface of the bobbinis provided with a component holding section for holding high-voltage components such as a capacitorand a diodewhich constitute a voltage doubler rectifying circuit for rectifying a high voltage having a high frequency from the secondary winding
