Abstract: A wireless power feeding system that transmits and receives power between a power transmission coil and a power reception coil using the magnetic field resonance method. The power reception coil is configured to be capable of selecting a plurality of coil regions that have different numbers of coil windings in accordance with the connecting positions of a plurality of terminals provided at the power reception coil. A controller changes an inductance of the power reception coil by switching the plurality of terminals to mitigate the difference between a load side impedance, which is an impedance from the input end of the power transmission device to a circuit on the load side, and an input side impedance, which is an impedance from the input end of the power transmission device to a circuit on the AC power source side.
