Abstract

To provide a power storage device which can protect power storage cells from both a load inputted to a case in the vertical direction and a load inputted to the case in a direction perpendicular to the vertical direction.SOLUTION: A power storage device 1 comprises: a plurality of power storage stacks 100; a case 200; and a protection structure 300 which protects a plurality of power storage cells 110 from a load inputted to the case 200. Each of the power storage stacks 100 has: a first unit stack 101; a second unit stack 102; and a middle plate 103. The case 200 has a bottom wall 212, a top wall 222, and peripheral walls 214, 224. A vertical length of the protection structure 300 is greater than a vertical length of the plurality of power storage cells 110. The protection structure 300 is disposed between a pair of the middle plates 103 adjacent to each other in the perpendicular direction.SELECTED DRAWING: Figure 3
