Zusammenfassung:To provide a power storage element which allows improvement in reliability.SOLUTION: A power storage element 10 comprises: a container 100; and an electrode body 700 housed in the container 100. The power storage element 10 further comprises: a shaft part 202 penetrating a lid body 120 of the container 100; a first collector 510 which is disposed inside the container 100 and which has a first connection part 512 connected to the shaft part 202; and a second collector 520 which has a second connection part 522 connected to the electrode body 700. The first connection part 512 and the second connection part 522 are juxtaposed in a direction intersecting an axial direction of the shaft part 202. The second collector 520 is bonded to the first collector 510 in such a state that the same comes into contact at least with a first region 513, of the first collector 510, located on an opposite side to the second connection part 522 across the first connection part 512.SELECTED DRAWING: Figure 2 【課題】信頼性の向上を図ることができる蓄電素子を提供すること。【解決手段】蓄電素子10は、容器100及び容器100に収容された電極体700を備える。蓄電素子10はさらに、容器100の蓋体120を貫通する軸部202と、容器100の内部に配置され、軸部202に接続された第一接続部512を有する第一集電体510と、電極体700に接続された第二接続部522を有する第二集電体520とを備える。第一接続部512及び第二接続部522は、軸部202の軸方向と交差する方向に並んで配置されている。第二集電体520は、少なくとも、第一集電体510における、第一接続部512を挟んで第二接続部522と反対側の第一領域513と接触した状態で、第一集電体510と接合されている。【選択図】図2
