Provided is a power storage device including: a stacked body constituted by stacking a plurality of electrodes including a current collector and an active material layer provided on the current collector; a sealing portion that surrounds the stacked body and seals between the electrodes adjacent in a stacking direction of the stacked body; a plurality of detection lines which are connected to the electrodes and are led out from the sealing portion to the outside; and a cooling member that is in contact with the stacked body and includes a cooling flow passage through which a cooling fluid is allowed to circulate from an inlet port to an outlet port in a direction intersecting the stacking direction. The sealing portion includes a leading-out portion through which each of the plurality of detection lines is led out, and the leading-out portion is located to be closer to the inlet port in relation to the outlet port of the cooling flow passage when viewed from the stacking direction.
