A wireless power reception device includes: a power receiving coil coupled to a transmitting coil; a first rectifier circuit rectifies AC voltage supplied from the receiving coil and outputs to a load; a first capacitor connected between 11th and 12th output terminals respectively on high and low potential sides among output terminals in the first rectifier circuit and the first rectifier circuit and the load; a second rectifier circuit connected to the receiving coil parallel to the first and rectifies AC voltage supplied from the receiving coil; a second capacitor connected between 21st and 22nd output terminals respectively on the high and low potential sides among second rectifier circuit output terminals; a second voltage detecting circuit detects voltage between the 21st and 22nd output terminals; and a position detecting circuit detects the receiving coil position relative to the power transmitting coil by voltage detected by the second voltage detecting circuit.
