PURPOSE: A multi output power supply apparatus is provided to saves a space for a printed circuit board by simplifying the circuit of a multi output power supply apparatus. CONSTITUTION: A multi output power supply apparatus(1) comprises a direct current voltage part(10) which applies a direct current voltage, a transformer(30), and a plurality of power output parts. A plurality of power output parts, which consists of a plurality of coils, is connected to the secondary side of the transformer. A plurality of the power output parts is composed of a main power output part(100a) and a secondary power output part(100b). A switching element(Q1), which is turned on/off according to a control signal, is connected to the primary side coil of the transformer. The direct current voltage of the direct current voltage part is changed into an AC voltage according to the on/off of the switching element. A diode for rectifying and a capacitor for smoothing are connected to the secondary side of the transformer.
