Abstract
A contactless electric power supply device of the present invention is provided with: multiple supply coils and an alternating current power source arranged on a fixed section; multiple receiving coils and a receiving circuit provided on a moving body; and a face-to-face power supply section provided for each of the multiple supply coils and configured to supply alternating current power from the alternating current power source to the supply coils only when detecting a face-to-face state between the supply coil and the receiving coil; wherein separation distances and lengths in the moving direction of the multiple supply coils and multiple receiving coils are set to satisfy face-to-face conditions, and a receiving circuit converts alternating current power received by at least one of the receiving coils in the face-to-face state and generates a receiving voltage at least equal to a driving voltage.
