A ground power supply device transmits power to a vehicle in a wireless manner includes: resonance circuits; and one power supply source that supplies AC power having the same frequency to all the resonance circuits. Each of the resonance circuits includes a coil embedded in a road and configured to transmit the power in a wireless manner, and a wiring connecting each of the coils and the power supply source. The wiring of each of the resonance circuits has a length at least partially different from the wiring of another resonance circuit, and inductance parasitic on the wiring is formed to be at least partially different from the wiring of the other resonance circuit due to a length difference. The resonance circuit includes a capacitor having a different electrostatic capacitance so that resonance frequencies of all the resonance circuits become equal when the inductance parasitic on the wiring is different.
A ground power supply device that transmits power to a vehicle in a wireless manner, the ground power supply device comprising:
A wiring used for a resonance circuit of a ground power supply device that includes a plurality of resonance circuits and one power supply source that supplies AC power having the same frequency to all the resonance circuits and transmits a power to a vehicle in a wireless manner, wherein
