1. A wireless electric power supply method comprising the operation of:

  • supplying electric power from a power supply section to a power-transmission resonance coil at a resonance frequency which causes magnetic field resonance;

    transmitting the electric power, supplied from the power supply section, as magnetic field energy from the power-transmission resonance coil to a power-reception resonance coil by using the magnetic field resonance, the power-transmission resonance coil being capable of being in magnetic field resonance with the power-reception resonance coil at the resonance frequency;

    monitoring the electric power supply by using a monitor section;

    comparing, by using a comparison section, the monitoring result obtained by the monitor section with characteristics data indicating the characteristics of the electric power supply performed by the power supply section; and

    controlling, by using a control section, the electric power supply performed by the power supply section, on the basis of the comparison result obtained by the comparison section.
