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 (T1) 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 (T4) 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).
