VEHICLE AND EXTERNAL POWER SUPPLY DEVICE

摘要

A vehicle-side self-resonant coil (110) provided on a vehicle is formed centered on a winding center (O2) so as to extend along the circumference of the winding center (O2). When the vehicle-side self-resonant coil (110) and an equipment-side self-resonant coil (240) are coupled by electromagnetic field resonant coupling, if a portion that becomes an antinode of the AC current flowing through the vehicle-side self-resonant coil (110) is set as an antinode portion (AM1) of the vehicle-side self-resonant coil (110), the distance between the antinode portion and the center of the vehicle is smaller than the distance between the winding center (O2) and the center of the vehicle.
