Here is disclosed a push-pull inverter characterized by a thin and small-sized boosting transformer improved to require a dielectric strength as low as possible and to be free from leakage current as well as noise. To realize such improvement, the boosting transformer is provided with a first secondary coil and a second secondary coil between which an impedance element such as a capacitor is connected so as to form together a serial circuit section, an output side of the first secondary coil is connected in a manner to have a same potential as a negative potential of a DC source and a load such as a fluorescent lamp is connected to the respective output sides of the first and second secondary coils.
