To prevent an overvoltage from being applied to a load in a power reception circuit of a power supply system. A power supply system is provided which includes a power supply device equipped with a power supply coil, and a power reception device equipped with a power reception coil. When a resonance circuit is in a resonance state, a peak voltage value of a voltage generated in the power reception coil is set higher than a prescribed voltage value. When the resonance circuit is in a non-resonance state, the peak voltage value of the voltage generated in the power reception coil is set lower than the prescribed voltage value.
