A wireless power supply system includes a power transmitter having a power-transmitting coil to which AC power of a frequency is input from a power source; and a power receiver having 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, in which the frequency, the coupling coefficient and the imaginary impedance are determined on the basis of satisfying a predetermined relationship.
