The method includes designing impedances of the power feeding (3) and The power receiving unit (5) to be small as a resonance frequency between the power feeding helical coil (33) and the power receiving helical coil (51) becomes small by adjusting impedances of the DC/AC converter (31) and the AC/DC converter (51).",
