CONDUCTOR ARRANGEMENT STRUCTURE FOR WIRELESS POWER SUPPLY SYSTEM

A conductor arrangement structure for a wireless power supply system which is equipped with a ground-side device (3) that is installed on a ground side and has a power-feeding coil (L1) and a vehicle-side device (2) that is installed on a vehicle (1) and has a power-receiving coil (L2) and in which electric power is supplied from the ground-side device (3) to the vehicle-side device (2) without contact, wherein grounding wires (23) are arranged between the power-feeding coil (L1) and the power-receiving coil (L2) so as to extend over a high-potential portion and a low-potential portion of an electric field that is generated when the power-feeding coil (L1) is excited.
