To provide a power storage device which can prevent damage to a power storage element.SOLUTION: A power storage device 10 comprises: a power storage element 200 and a first spacer 310 aligned in a first direction; and a side plate 500 disposed on one side, of the power storage element 200 and the first spacer 310, in a second direction intersecting the first direction. The first spacer 310 has: a spacer body 311 which faces a first surface (a longer-side surface 211) on one side, of the power storage element 200, in the first direction; and a protrusion 312 which protrudes from the spacer body 311 to the other side in the first direction and faces a second surface (a shorter-side surface 212) on one side, of the power storage element 200, in the second direction. The protrusion 312 is disposed between the second surface and the side plate 500 such that it is spaced away from the second surface.SELECTED DRAWING: Figure 7 【課題】蓄電素子の損傷を抑制することができる蓄電装置を提供する。【解決手段】蓄電装置１０は、第一方向に並んで配置される蓄電素子２００及び第一スペーサ３１０と、蓄電素子２００及び第一スペーサ３１０の、第一方向と交差する第二方向の一方側に配置されるサイドプレート５００と、を備え、第一スペーサ３１０は、蓄電素子２００の第一方向の一方側の第一面（長側面２１１）に対向するスペーサ本体３１１と、スペーサ本体３１１から第一方向の他方側に突出し、かつ、蓄電素子２００の第二方向の一方側の第二面（短側面２１２）に対向する突出部３１２と、を有し、突出部３１２は、第二面とサイドプレート５００との間に、第二面とは離間して配置される。【選択図】図７
