PROBLEM TO BE SOLVED: To simplify the assembly of a power storage module having a gas exhaust structure and obtain an appropriate sealing performance.SOLUTION: A power storage module according to the invention comprises: a plurality of power storage elements; a holder having a plurality of openings into which power storage elements are respectively inserted, and holding one end of each of the power storage elements extending in a predetermined direction; a cover member for defining an exhaust space for gas generated in each power storage element between the holder and it; and a seal member for sealing the exhaust space. The cover member is provided on the second surface side of the holder opposite the first surface side thereof, which faces the exhaust space in a direction in which the cover member is pressed by the pressure of gas. The cover member has a folding part that restricts its movement in a direction in which the cover member is pressed. The seal member is provided between the folding part and the second surface so as to surround the periphery of the plurality of power storage elements. When gas is expelled into the exhaust space, the seal member is compressed in the same direction as the direction in which it is pressed by the folding part.SELECTED DRAWING: Figure 3 |
