This contactless power supply device is equipped with: a power transmission coil for transmitting power in a contactless manner to a power-receiving coil which is electrically connected to a load; an inverter for converting power from a power source into AC power, and outputting the AC power to the power transmission coil; and a control means for setting a plurality of inverter drive frequencies, and driving the inverter using a varying control for varying the frequency when driving the inverter. The inverter is connected between the power transmission coil and the power source. The drive frequencies are a plurality of discrete frequencies. In addition, during the frequency-varying control, the control means varies the frequency when driving the inverter by repeating the plurality of drive frequencies. |
