Disclosed is a vehicle guidance apparatus that can easily guide a vehicle in the vicinity of a power supply section to the power supply unit by guiding the vehicle along a path of travel to the power supply unit without employing image data. In this device, a power supply efficiency calculation unit calculates the power supply efficiency, which is the efficiency with which power is received from the power supply unit by the charging unit. An amount of change calculation unit calculates the amount of change of efficiency of power supply, which is the amount of change of efficiency of power supply calculated by the power supply efficiency calculation unit. A vehicle-side control unit displays on a display guidance to enable the vehicle to reach the power supply unit, based on the amount of change of efficiency of power supply calculated by the amount of change calculation unit.
