PROBLEM TO BE SOLVED: To provide a highly reliable photocell becoming an energy source using extreme ultraviolet light, and applicable sufficiently even to a use environment requiring mobility with a simple device configuration.SOLUTION: A photocell includes a photocathode 11 irradiated with EUV light and emitting photoelectrons, an anode 12 for capturing the photoelectrons emitted from the photocathode 11, and a capacitor 13 connected between the photocathode 11 and anode 12, and in which charges are stored by a photocurrent thus generated. Electrical energy is taken out from the capacitor 13. 【課題】簡素な装置構成で機動性を要求される使用環境にも十分に適応する、極紫外光を利用したエネルギー源となる信頼性の高い光電池を提供する。【解決手段】光電池は、ＥＵＶ光が照射されて光電子を放出する光カソード１１と、光カソード１１から放出された光電子を捕集するアノード１２と、光カソード１１とアノード１２との間に接続されており、発生した光電流により電荷蓄積されるキャパシタ１３とを備えており、キャパシタ１３から電気エネルギーが取り出される。【選択図】図２
