PROBLEM TO BE SOLVED: To provide a power storage device capable of cutting off current in overcharging etc., by placing a current cutoff device in operation more securely with hydrogen produced from a hydrogen occlusion alloy, and a vehicle mounted with the power storage device.SOLUTION: A power storage device includes: a sheet-like separator; an electrode body having a positive electrode sheet and a negative electrode sheet formed at positions opposite each other across the separator; a hydrogen occlusion member disposed at least partially in the electrode body, coming into contact with at least one of the positive electrode sheet and the negative electrode sheet, and including a hydrogen occlusion alloy in a hydrogen occluding state; a case housing the electrode body and the hydrogen occlusion member; and a current cutoff device which cuts off current by operating with pressure as the pressure in the case rises. |
