To provide a power storage element capable of smoothly inserting an electrode body into a container body, and a manufacturing method thereof.SOLUTION: A power storage element 10 includes an electrode body 700 having laminated electrode plates and a container housing the electrode body. The container includes a container body 160 and a container lid 170. The container body has a first wall part 161 facing the electrode body in a lamination direction of the electrode plates, and a second wall part 162 rising from the entire periphery of the first wall part. The container lid is joined to the second wall part while closing an opening formed by the second wall part.SELECTED DRAWING: Figure 2 【課題】電極体を容器本体内にスムーズに挿入可能な蓄電素子及びその製造方法を提供する。【解決手段】蓄電素子１０は、積層された極板を有する電極体７００と、電極体を収容する容器と、を備え、容器は、容器本体１６０と容器蓋体１７０とを備え、容器本体は、極板の積層方向で電極体と対向する第一壁部１６１と、第一壁部の全周縁から立ち上がる第二壁部１６２と、を備え、容器蓋体は、第二壁部がなす開口を塞いだ状態で当該第二壁部に接合されている。【選択図】図２
