A ground power supply apparatus for transmitting power to a vehicle by noncontact has: a plurality of power transmission apparatuses for transmitting power to the vehicle; at least one detection device for detecting a signal emitted from the vehicle using narrow range wireless communication; and a controller for controlling the power transmission apparatuses. The power transmission apparatuses are arranged in a road aligned in a direction of advance of the vehicle. One first detection device is arranged so as to enable detection of the signal at an upstream side from the most upstream power transmission apparatus. The control device controls transmission of power from power transmission apparatuses other than the first power transmission apparatus positioned the most upstream, based on the signal detected by the first detection device and power transmission result information at the power transmission apparatus positioned upstream of that power transmission apparatus.
