  "textContent": "A wireless power supply system (100) that wirelessly supplies power to a mobile body (200) including a power receiving unit (280) includes an AC power supply unit (20) and a plurality of power transmission units (80), the plurality of power transmission units are disposed in at least a part of a moving range of the moving body and include a power transmission coil (81). The wireless power supply system includes a plurality of power transmission units that receive a supply of power from the AC power supply unit and supply power to a power receiving unit via the power transmission coil in a resonance state, and a switching control unit that switches a state of a first power transmission unit (80a) to a resonance state when the magnitude of the magnetic flux generated in a first power transmission coil (81a) of the first power transmission unit, which is one of the plurality of power transmission units, is greater than a predetermined threshold value, and switches to a non-resonance state when the magnitude is less than the threshold value. The threshold is set as a magnitude that exceeds the magnetic flux generated in the first power transmission coil due to a coupling between the first power transmission coil and a second power transmission coil (81b) of a second power transmission unit (80b), which is adjacent to the first power transmission coil.",
