Claim 0:
1. A non-contact power feeding device comprising:
a power transmitter device; and
a power receiver device to which the power transmitter device transmits power in a non-contact manner, wherein
the power transmitter device comprises:
a transmitter coil configured to supply power to the power receiver device;

and
a power supply circuit configured to supply AC power to the transmitter coil,

the power receiver device comprises:
a plurality of resonance circuits configured to receive power from the transmitter coil of the power transmitter device; and
a power receiver circuit configured to output, to a load circuit, the power received from the power transmitter device by the plurality of resonance circuits, each of the plurality of resonance circuits comprises:
a receiver coil configured to receive power from the power transmitter device, and a resonance capacitor configured to resonate, together with the receiver coil, with the AC power supplied to the transmitter coil; and
the receiver coils of the plurality of resonance circuits are arranged so as to be electromagnetically coupled to each other, and

a first resonance circuit among the plurality of resonance circuits is connected to the power receiver circuit, the receiver coil and the resonance capacitor of the first resonance circuit are connected in parallel, and the receiver coil and the resonance capacitor of each resonance circuit other than the first resonance circuit among the plurality of resonance circuits, are connected in series.
