PROBLEM TO BE SOLVED: To provide a power storage device that detects an abnormality (leakage of a liquid electrolyte) in storage elements at an early stage.SOLUTION: A power storage device (1) has: a plurality of storage elements (10) that each include a liquid electrolyte and that are charged and discharged; and a holder (30) that holds the storage elements (10) in a predetermined plane (a Y-Z plane) while being insulated from the storage elements (10). The holder (30) has conductive members (31, 34) that are exposed to the outside of the holder (30) and that are positioned in a direction in which the liquid electrolyte leaking from each storage element (10) moves. The conductive members (31, 34) are connected to a sensor (100) that detects a conductive state and a non-conductive state thereof. |
