PROBLEM TO BE SOLVED: To provide a non-contact power supply device capable of stably supplying desired power to various loads, from light loads to heavy loads. SOLUTION: The non-contact power supply device 1 is constructed of a primary circuit 11 and a secondary circuit 12, connected together via a transformer 2 constructed of a power-transmitting coil 21 and a power-receiving coil 22. The primary circuit 11 includes at least a regulator circuit 6 and an inverter circuit 5. The regulator circuit 6 is provided with current-detecting means 7 for detecting the current that passes through the inverter circuit 5; and an output voltage control circuit 8 that lowers the input voltage to the inverter circuit 5, when the detected current value of the inverter circuit 5 is lower than an arbitrary predetermined current value, and raises the input voltage to the inverter circuit 5, when the detected current value is higher.
