POWER STORAGE MODULE

A power storage module includes a module main body having an electrode stack in which a plurality of electrodes are stacked; and a pressure control valve attached to the module main body. The pressure control valve includes a housing having a first wall that has a communication hole, a second wall, and a first protrusion formed in the second wall, and a valve body accommodated in the housing so as to close the communication hole. The second wall has a first hole that is opened at an outer surface of the second wall, and a second hole that is opened at the outer surface, the second hole being positioned vertically above the first hole. The first protrusion protrudes outward from the outer surface along a first direction, and extends so as to partition between the first hole and the second hole, as viewed in the first direction.
