In a push-pull switching circuit for a low-voltage, large current application, a decrease in resistance of a transformer and of its peripheral circuit is sought for. In view of this, a coil ( 2 ) is fixed at its terminal (T 1 ) side, and is wound around a columnar winding core ( 1 ) counterclockwise in the order of a lower surface (H), side surface (I), upper surface (J), side surface (K), and the lower surface (H). A coil ( 3 ) is fixed at its terminal (T 4 ) side, and is wound clockwise in the order of the upper surface (J), side surface (I), lower surface (H), side surface (K), and upper surface (J).
