To provide a non-contact power supply device and a non-contact power supply system including the same, and a non-contact power supply method that can stabilize the communication state with a power receiving device to perform power supply in a stable state.SOLUTION: A non-contact power supply device 10 is a device that performs communication with a power receiving device 20 and performs power supply to the power receiving device 20, and comprises a power supply coil unit 13, a radio communication unit 16, and a power supply control unit 15. The power supply coil unit 13 performs power supply to the power receiving device 20. The radio communication unit 16 performs communication with the power receiving device 20. The power supply control unit 15 compares a reference value set when reception of data transmitted from the power receiving device 20 is started in the radio communication unit 16 with the field intensity included in the data received after the setting of the reference value, and when the field intensity is smaller than the reference value, performs correction to increase an output value of the power supply from the power supply coil unit 13 to the power receiving device 20.SELECTED DRAWING: Figure 1 【課題】受電装置側との通信状態を安定化させ、安定した状態で給電を実施することが可能な非接触給電装置およびこれを備えた非接触給電システム、非接触給電方法を提供する。【解決手段】非接触給電装置１０は、受電装置２０と通信を行い受電装置２０へ給電する装置であって、給電コイル部１３と、無線通信部１６と、給電制御部１５とを備えている。給電コイル部１３は、受電装置２０へ給電を行う。無線通信部１６は、受電装置２０と通信を行う。給電制御部１５は、無線通信部１６において受電装置２０から送信されたデータの受信が開始された際に設定された基準値と、基準値の設定後に受信したデータに含まれる電波強度とを比較して、電波強度が基準値よりも小さい場合に、給電コイル部１３から受電装置２０へ給電される出力値を大きくする補正を行う。【選択図】図１
