To provide a wireless power supply system that prevents people from being exposed to strong radio waves for a long time.SOLUTION: A wireless power supply system includes a determination unit that determines whether there is a person in a predetermined area by fluctuation in radio wave strength of at least any of a radio wave of wireless power supply and a radio wave used for communication. A power supply unit implements wireless power supply at a second power amount or less that is less than a first power amount or stops wireless power supply to a remote control device, at least when the determination unit determines that there is a person in the predetermined area.SELECTED DRAWING: Figure 1 【課題】人が強い電波を長時間受けることを抑制するワイヤレス給電システムを提供する。【解決手段】所定領域に人が存在するか否かを、ワイヤレス給電の電波及び通信に用いられる電波の少なくともいずれかの電波強度の変動により判定する判定部を備え、前記給電部は、少なくとも前記判定部が前記所定領域に人が存在すると判定した場合には、前記第１電力量未満の第２電力量以下でワイヤレス給電を実施する、又は、前記遠隔制御装置に対するワイヤレス給電を停止するワイヤレス給電システムである。【選択図】図１
