PROBLEM TO BE SOLVED: To reliably suppress local stress with a simple and economical structure.SOLUTION: An end plate 18a forming a power storage module 10 is made up of an outer metal plate 26a and an inner metal plate 28a. The inner metal plate 28a and the outer metal plate 26a form a closed cross section 38a via their contact parts overlapping each other in a lamination direction. At least at the contact parts, the outer metal plate 26a has a protrusion end 40a which protrudes more in a direction facing a connection bar than the inner metal plate 28a does.SELECTED DRAWING: Figure 3 |
