Abstract
A contactless power feed system includes a first ground power feed device and a second ground power feed device for performing contactless power feed to a moving body. The first ground power feed device transmits a passing signal to the second ground power feed device when entry of the moving body to a first power feed section is confirmed. The second ground power feed device transmits a power feed stop signal to the first ground power feed device when confirmation of entry or approach of the moving body to a second power feed section is not possible even after a predetermined time has elapsed after receiving the passing signal.
