PROBLEM TO BE SOLVED: To provide a method that, during power transmission via a variable magnetic field between a coil of a feeding module and a coil of a receiving module, intentionally forms a magnetic field space having a low magnetic field strength in a desired position about the coils by blocking a magnetic field generated about the coils.SOLUTION: With a feeding resonator 22 of a feeding module 202 and a receiving resonator 32 of a receiving module 203 arranged oppositely, and cylindrical magnetic members 23, 33 arranged on coil inner circumferences of the feeding resonator 22 and the receiving resonator 32 so as to cover the entire coil inner circumferences of the feeding resonator 22 and the receiving resonator 32, a magnetic field is changed between the feeding resonator 22 and the receiving resonator 32 for power transmission, so that the magnetic members 23, 33 block a magnetic field generated about the feeding resonator 22 and the receiving resonator 32 to form a magnetic field space Z having a lower magnetic field strength than the outside of the coil inner circumferences on the coil inner circumferences of the feeding resonator 22 and the receiving resonator 32. |
