To provide a power storage device capable of attaining reduced manufacturing cost, high energy density, and space saving.SOLUTION: A power storage device includes a stack of a plurality of power storage cells stacked in a first direction, and a case that accommodates the stack. The case includes: a first portion and a second portion facing respective end surfaces of the stack along the first direction; a third portion and a fourth portion facing respective side surfaces of the stack along a second direction orthogonal to the first direction; and a fifth portion and a sixth portion respectively facing an upper surface and a bottom surface of the stack along a third direction orthogonal to the first direction and the second direction. The first portion and the second portion are in abutment with the respective end surfaces of the stack, and each receive force from the stack in the first direction. The stack is supported by the case along the first direction with the force received by the first portion and the second portion in the first direction being transmitted to all of the third portion to the sixth portion.SELECTED DRAWING: Figure 6 【課題】製造コスト削減、高エネルギー密度化、および省スペース化が可能な蓄電装置を提供する。【解決手段】蓄電装置は、第１方向に積層された複数の蓄電セルの積層体と、積層体を収容するケースとを備える。ケースは、第１方向に沿って積層体の両端面に各々対向する第１部分および第２部分と、第１方向に直交する第２方向に沿って積層体の両側面に各々対向する第３部分および第４部分と、第１方向および第２方向に直交する第３方向に沿って積層体の上面および底面に各々対向する第５部分および第６部分とを含む。第１部分および第２部分は、積層体の両端面に各々当接し、積層体から第１方向の力を受ける。第１部分および第２部分が受けた第１方向の力が第３部分ないし第６部分の全てに伝達されることにより積層体が第１方向に沿ってケースに支持される。【選択図】図６
