PROBLEM TO BE SOLVED: To provide a power storage element capable of increasing a capacity by ensuring a large proportion of an electrode body occupied in a container.SOLUTION: The power storage element includes an electrode body 400, a collector and a container 100 storing the electrode body 400 and the collector. The container 100 has a recessed part 112 on an inner surface. At least part of a connection part between the electrode body 400 and the collector or at least part of a connection part between a conductive member connected with the electrode body 400 and the collector is disposed at a position opposing to the recessed part 112.SELECTED DRAWING: Figure 10 【課題】容器内に占める電極体の発電部分の割合を大きく確保して、容量の増加が図られる蓄電素子を提供する。【解決手段】電極体４００と、集電体と、電極体４００及び集電体を収容した容器１００とを備える蓄電素子であって、容器１００は、内面に凹部１１２を有し、電極体４００と集電体とが接続される部分の少なくとも一部または電極体４００に接続された導電部材と集電体とが接続される部分の少なくとも一部は、凹部１１２に対向する位置に配置されている。【選択図】図１０
