VEHICLE AND EXTERNAL POWER SUPPLY DEVICE

A vehicle self-resonant coil (110) provided at a vehicle is formed to extend along a circumference of a winding center (02), centered about the winding center (02). The distance between the center of the vehicle and an anti-node (AM1) of the vehicle self-resonant coil (110) that is the area of the anti-node of AC current flowing through the vehicle self-resonant coil (110) when electromagnetic field resonant coupling is established between the vehicle self-resonant coil (110) and the facility self-resonant coil (240) is shorter than the distance between the winding center (02) and the center of the vehicle.
