A wireless power feeding system includes a plurality of power transmission antennas, each including a resonance circuit including a power transmission coil and a capacitor located so as to generate a magnetic field in a desired direction, a controller controlling a resonant state of each of the plurality of power transmission antennas, a plurality of driving units applying an AC voltage to the plurality of power transmission antennas to drive each of the plurality of power transmission antennas, and a power supply supplying a voltage to the plurality of driving units. The controller controls a power transmission antenna from which a magnetic field is to be generated to place the power transmission antenna in a resonant state and controls a power transmission antenna from which a magnetic field is not to be generated to place the power transmission antenna in a nonresonant state.
