Disclosed herein is a wireless power receiving device that wirelessly receives power transmitted from a wireless power transmitting device. The wireless power receiving device comprises: a power receiving coil that receives an AC power through a magnetic field; a power-receiving-side capacitor that constitutes a resonance circuit together with the power receiving coil; a rectifying circuit that rectifies the AC power received by the power receiving coil by a plurality of bridge-connected semiconductor devices each having a rectifying function; and a short-circuit detection circuit that detects a short circuit in the rectifying circuit based on a first AC voltage which is a voltage between a one-side input line of the rectifying circuit and a stable potential and a second AC voltage which is a voltage between the other-side input line of the rectifying circuit and the stable potential.
