PROBLEM TO BE SOLVED: To efficiently drive a transmitting antenna in resonance frequency at all times by being able to control drive frequency to accord with the resonance frequency at all times even if slippage occurs between the resonance frequency of the transmitting antenna and the drive frequency.
SOLUTION: This wireless power supply system 1 has the transmitting antenna 4 for sending power by wireless to the side of a receiving antenna 21, an oscillator 9 which generates a clock signal for driving the transmitting antenna 4, a drive circuit 7 which drives the transmitting antenna 4, based on the clock signal from the oscillator 8, a drive voltage source 8 for supplying the transmitting antenna 4 with a drive voltage, a temperature detector 6 which detects the temperature of a capacitor 5 for resonance for getting the resonance frequency fr of the transmitting antenna 4, and a controller 10 which controls the oscillator 9 so that the drive frequency may accord with the above resonance frequency fr by deciding the resonance frequency fr of the transmitting antenna 4, based on the detection results by the temperature detector 6.
