With the present invention, it is possible to form a magnetic field space (Z) having a relatively small magnetic field intensity between a power supply resonator (22) and a power receiving resonator (32), by supplying electrical power from the power supply resonator (22) to the power receiving resonator (32) by a resonance phenomenon. When doing so, the formation location of the magnetic field space (Z) can be changed by setting the frequency of the alternating current power, supplied from an alternating current power source to a power supply module (2), to an opposite-phase resonance mode or to a same-phase resonance mode. Also, the size of the magnetic field space (Z) can be changed by changing the distance (A) between a power supply coil (21) and the power supply resonator (22) and the distance (B) between the power receiving resonator (32) and a power receiving coil (31). |
