A power receiver apparatus receives a code-modulated wave from a power transmitter apparatus via a transmission path, the code-modulated wave including first power modulated by code modulation using a modulation code based on a code sequence. The power receiver apparatus is provided with a contactless connector and a code demodulator. The contactless connector is coupled to the transmission path without electrical contact with the transmission path, and receives the code-modulated wave from the power transmitter apparatus via the transmission path. The code demodulator demodulates the received code-modulated wave to generate second power by code demodulation using a demodulation code based on a code sequence identical to the code sequence of the modulation code used for the code modulation.
