An ECU in a failure determination apparatus receives a wireless LAN signal from a power-transmission-side wireless communication unit with a vehicle-side wireless communication unit and determines whether a relative position acquisition system fails based on whether predetermined expressions are established for the respective reception intensities of a low frequency signal at first to fourth power-transmission-side antennas, which are included in the wireless LAN signal.
