A wireless power supply system includes a power transmitter and a power receiver. The power transmitter includes a power-transmitting coil to which AC power of a frequency is input from a power source. The power receiver includes a power-receiving coil magnetically coupled to the power-transmitting coil at a coupling coefficient, and a first power-receiving-side series element coupled in series to the power-receiving coil and having imaginary impedance jZS2i. In this wireless power supply system, the frequency and the imaginary impedance are determined so that impedance of a power-receiving side seen from the power source is independent of the coupling coefficient when the coupling coefficient changes.
