To improve power generation efficiency.SOLUTION: A power generation device A1 includes a first vibration body 10, a first generation body 12, a movable part 2, a vibration body stopper 4A, a body 30, a core 31, and a coil 32. The movable part 2 moves downward in a state in which an end portion of the first vibration body 10 and the core 31 are sucked by magnetic attraction. As the movable part 2 moves downward, the end portion of the first vibration body 10 contacts the vibration body stopper 4A. As the movable part 2 moves further downward from a state in which the end portion of the first vibration body 10 is in contact with the vibration body stopper 4A, the movable part 2 is separated from the end portion of the first vibration body 10 and the core 31. When the movable part 2 moves away from the end portion of the first vibration body 10 and the core 31, an induced electromotive force is generated in the coil 32.SELECTED DRAWING: Figure 1 【課題】発電効率の向上を図る。【解決手段】発電装置Ａ１は、第１振動体１０と、第１発電体１２と、可動部２と、振動体ストッパ４Ａと、ボディ３０と、コア３１と、コイル３２とを備える。可動部２は、第１振動体１０の端部とコア３１を磁気吸引力によって吸着した状態で下方向に移動する。可動部２が下方向に移動することで、第１振動体１０の端部が振動体ストッパ４Ａに接触する。第１振動体１０の端部が振動体ストッパ４Ａに接触している状態から可動部２が更に下方向へと移動することで、第１振動体１０の端部及びコア３１から可動部２が離れる。第１振動体１０の端部及びコア３１から可動部２が離れたときに、コイル３２に誘導起電力を生じさせる。【選択図】 図１
