Abstract
A power storage module includes a stack formed of electrodes stacked each including a current collector and an active material layer, a seal portion defining internal spaces, communication holes providing communication between the internal spaces and an outside, and a sheet member sealing the communication holes individually and cleaved to release internal pressure in the respective internal spaces. The sheet member has facing portions and a joint portion joined to the seal portion. The respective facing portions have stress concentrating portions. Cleavage pressure, which is the internal pressure applied to corresponding one of the facing portions when one of the stress concentrating portions is cleaved, is lower than peeling pressure, which is the internal pressure applied to corresponding one of the facing portion when the joint portion is peeled off from the seal portion.
