Zusammenfassung:	To provide a power storage device which can improve safety when an abnormality of a power storage cell is detected or predicted.SOLUTION: A power storage device 20 comprises: a power storage cell 26 formed into a plate-like shape; and a cell binding part 60 which applies binding pressure to the power storage cell 26 in a plate thickness direction. When an abnormality of the power storage cell 26 has been detected or predicted, the cell binding part 60 is deformed so as to reduce the binding pressure.SELECTED DRAWING: Figure 3 【課題】蓄電セルの異常検知時又は予知時における安全性を向上させることができる蓄電デバイスを得る。【解決手段】蓄電デバイス２０は、板状に形成された蓄電セル２６と、蓄電セル２６に対して板厚方向に沿って拘束圧を付与するセル拘束部６０と、を備える。このセル拘束部６０は、蓄電セル２６の異常が検知又は予知された場合に変形し、拘束圧を低減させるように構成されている。【選択図】図３
