Summary:PROBLEM TO BE SOLVED: To provide a power storage apparatus capable of preventing contact of an external terminal of a power storage element with an external terminal of the other power storage element even when compression force is applied in an arrangement direction of the power storage elements.SOLUTION: The power storage apparatus includes: a plurality of power storage elements aligned in a first direction and respectively having external terminals in a second direction orthogonal to the first direction; a plurality of spacers respectively arranged between the adjacent power storage elements; and a frame for holding the plurality of power storage elements and the plurality of spacers. Rigidity in the first direction, of a portion of the spacer on the opposite side to the external terminal side is lower than rigidity in the first direction, of a portion of the spacer on the external terminal side. 【課題】 蓄電素子が並ぶ方向での圧縮力が作用しても蓄電素子の外部端子が他の蓄電素子の外部端子と接触することを防止することができる蓄電装置を提供することを課題とする。【解決手段】 本発明に係る蓄電装置は、第一方向に整列され且つそれぞれが第一方向と直交する第二方向に外部端子を有する複数の蓄電素子と、隣り合う蓄電素子間にそれぞれ配置される複数のスペーサと、複数の蓄電素子及び前記複数のスペーサを保持するフレームとを備え、スペーサにおける外部端子側とは反対側の部分の第一方向における剛性がスペーサにおける外部端子側の部分の第一方向における剛性よりも低くなっている【選択図】図3
