1. A non-contact power feeding apparatus, comprising:
- a secondary winding to which an electric power is supplied from a primary winding in a non-contact manner by an alternating-current power source;
a first circuit section connected in parallel to the secondary winding and configured to form a first resonant circuit with the secondary winding; and
a second circuit section connected in series to a parallel circuit of the secondary winding and the first circuit section and configured to form a second resonant circuit with the secondary winding different from the first resonant circuit, whereinthe second circuit section includes a battery,a magnitude of an impedance of the first circuit section is larger than a magnitude of an impedance of the second circuit section,wherein the first circuit section includes a first capacitor, andthe second circuit section includes a second capacitor, andwherein

Abstract
There are provided with: a secondary winding 20 to which an electric power is supplied in a non-contact manner from a primary winding 10 by an alternating-current power source; a first circuit section 21 connected in parallel to the secondary winding 20; and a second circuit section 22 connected in series to a parallel circuit of the secondary winding 20 and the first circuit section 21. An impedance of the first circuit section 21 is larger than an impedance of the second circuit section.
