Abstract:
This contactless electricity supply device, which contactlessly performs charging of the battery (28) of a vehicle, is provided with: an electricity transmission coil (12) disposed at a road surface; and an electricity reception coil (22) disposed in the vehicle. A foreign object detection coil (13) is provided to the upper surface of the electricity transmission coil (12), and on the basis of induced voltage arising at the foreign object detection coil (13) during a trial electricity supply, foreign objects between the electricity transmission coil (12) and the electricity reception coil (22) are detected.
