PROBLEM TO BE SOLVED: To provide a power storage device in which a plurality of rows of power storage element group are entirely held stably, even if there is a dimensional error of the plurality of arranged power storage elements in the row direction.SOLUTION: A power storage element group arranged in a first direction forms a plurality of rows perpendicular to the first direction. A holding member 3 for holding the plurality of rows of power storage element group includes a pair of end members 30 arranged on both sides of the plurality of rows of power storage element group in the first direction, and a coupling member 31 for connecting the pair of end members 30, where at least one of the pair of end members 30 has a plurality of protrusions 300 facing the plurality of rows of power storage element group. The end member 30 has a connection 30B interconnecting adjacent holding parts 30A, and the connection 30B is deformable in the first direction.SELECTED DRAWING: Figure 4 |
