Abstract
As an aspect of the present invention, a noncontact power feeding apparatus includes: a power transmission resonator; and a power reception resonator configured to be magnetically coupled with the power transmission resonator by magnetic field resonance. The power transmission resonator is magnetically coupled with the power reception resonator by the magnetic field resonance, whereby electric power is supplied from an electric power source to the power reception resonator through the power transmission resonator. One of the power transmission resonator and the power reception resonator has a predetermined single resonant frequency, and the other one of the power transmission resonator and the power reception resonator has multiple resonant frequencies inclusive of the predetermined single resonant frequency.
