POWER STORAGE MODULE

A power storage module includes a module main body in which electrodes are stacked in a first direction, a frame, and a pressure control valve attached to the frame having first communication holes in communication with internal spaces. The pressure control valve includes a wall body that has second communication holes in communication with the first communication holes, respectively, a protrusion that surrounds each of the second communication holes separately, the second communication holes being opened at a first wall surface, and valve bodies that close the second communication holes. A recess is formed to be recessed in a direction away from the frame and along the valve bodies, in a region of the first wall surface surrounded by the protrusion and having an opening of one of the second communication holes, the region not overlapping with the valve bodies as viewed in a second direction.
