Abstract
A contactless power feeding apparatus includes a secondary winding to which power is supplied from a primary winding by an AC power supply. An impedance absolute-value characteristic of Zhas a frequency of a fundamental wave component to be between a frequency where a local maximum exists and that is nearest to the frequency of the fundamental wave component, and a frequency where a local minimum exists and that is nearest to the frequency of the fundamental wave component. An impedance absolute-value characteristic of Zhas the frequency of the fundamental wave component to be between a frequency where the local maximum exists and that is nearest to the frequency of the fundamental wave component, and a frequency where the local minimum exists and that is nearest to the frequency of the fundamental wave component.
