Abstract
A wireless electric power supply method includes: 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.
