To provide a method for transmitting electric power easily, completely and safely in use under an environment such as at the sea, under the sea or in a water-wet state and further in such a scene that use of a metal contact is undesired, for example, for the purpose of prevention of leakage of electricity or explosion-proofing.SOLUTION: The device group transmitting electric power in a non-contact manner transmits an optical pulse of a frequency compatible with a voltage of electric power supplied from a power reception side device to a load RC4 from an optical pulse emission device R14 to a power transmission side device S, and in the power transmission side device, maintains a voltage of power transmitted to a load by the power reception side device to be contact (a target value) by increasing and decreasing the quantity of high-frequency power to interpret and transmit characteristics of the optical pulse received by an optical pulse reception device S14 or by executing a delivery stop.SELECTED DRAWING: Figure 1 【課題】海面、海中あるいは水濡れのある環境での使用、更には漏電防止や防爆目的など、金属接点を用いたくない場面で、電力を簡便・確実・安全に伝送する方法や係る装置を提供する。【解決手段】非接触で電力を送る装置群において、受電側装置Ｒから負荷ＲＣ４に供給する電力の電圧に対応した周波数の光パルスを光パルス発光器Ｒ１４から送電側装置Ｓに伝え、送電側装置では光パルス受光器Ｓ１４で受けた光パルスの特性を解釈して送出する高周波電力の量を増減、あるいは送出停止することで受電側装置が負荷に送出する電力の電圧を一定（目標値）に保つ。【選択図】図１
