A power-supplying resonator 22 of a power-supplying module 202 and a power-receiving resonator 32 of a power-receiving module 203 are arranged to face each other. On inner circumferential surface sides of the power-supplying resonator 22 and the coil of the power-receiving resonator 32, cylindrical magnetic member 23 and 33 which cover the entire inner circumferential surface of the coils of the power-supplying resonator 22 and the power-receiving resonator 32 are arranged. By conducting power transmission between the power-supplying resonator 22 and the power-receiving resonator 32 while varying a magnetic field, the magnetic field occurring around the power-supplying resonator 22 and the power-receiving resonator 32 is shielded by the magnetic members 23 and 33, and there is formed, on the coil inner circumferential surface sides of the power-supplying resonator 22 and the coil of the power-receiving resonator 32, a magnetic field space Z whose magnetic field strength is smaller than the magnetic field strength of areas other than the inner circumferential surface sides. |
