1. A vehicle comprising:
- a vehicle self-resonant coil establishing electromagnetic field resonant coupling with a facility self-resonant coil provided external to the vehicle, allowing reception of electric power from said facility self-resonant coil,said vehicle self-resonant coil formed to extend along a circumference of a winding center, centered about the winding center,a distance between the center of said vehicle and an anti-node of said vehicle self-resonant coil that is an area of an anti-node of AC current flowing through said vehicle self-resonant coil when electromagnetic field resonant coupling is established between said vehicle self-resonant coil and said facility self-resonant coil is shorter than the distance between said winding center and the center of said vehicle.

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

8. An external power feeding apparatus provided at a parking space where a vehicle including a vehicle self-resonant coil parks at a predetermined position, said external power feeding apparatus comprising:
-
a facility self-resonant coil establishing electromagnetic field resonant coupling with said vehicle self-resonant coil to transmit electric power to said vehicle self-resonant coil, said vehicle self-resonant coil formed winding about a winding center, a distance between the center of said vehicle and an anti-node of said vehicle self-resonant coil that is an area of an anti-node of AC current flowing through said vehicle self-resonant coil when electromagnetic field resonant coupling is established between said vehicle self-resonant coil and said facility self-resonant coil is shorter than the distance between said winding center and the center of said vehicle, and when said vehicle parks at said predetermined position, the anti-node of said vehicle self-resonant coil and an anti-node of said facility self-resonant coil that is an area of an anti-node of AC current flowing through said facility self-resonant coil when electromagnetic field resonant coupling is established between said vehicle self-resonant coil and said facility self-resonant coil, are aligned in a height direction.
