PROBLEM TO BE SOLVED: To provide a power reception apparatus capable of improving efficiency of a rectification unit, and a non-contact power transmission device having the power reception apparatus.SOLUTION: A non-contact power transmission device 10 comprises: a ground side apparatus 11 installed on the ground; and a vehicle side apparatus 21 mounted on a vehicle. The ground side apparatus 11 comprises a high-frequency power supply 12 and a power transmitter 13 to which high-frequency power is input from the high-frequency power supply 12. The vehicle side apparatus 21 comprises: a power receiver 23 capable of receiving high-frequency power from the power transmitter 13 in a non-contact manner; a rectifier 24 for rectifying the high-frequency power received by the power receiver 23; a DC/DC converter 25 for converting a voltage value of DC power rectified by the rectifier 24, where a load impedance Z1, which is impedance from an output end of the rectifier 24 to the vehicle battery 22, is adjusted so that efficiency of the rectifier 24 is high. |
