POWER STORAGE ELEMENT AND METHOD FOR MANUFACTURING THE SAME

To provide a power storage element capable of achieving space saving.SOLUTION: A power storage element 10 includes a container 100, an electrode terminal 200, an electrode body 600, and a current collector 500 disposed on a first direction side of a wall part of the container 100 and connected to the electrode terminal 200 and the electrode body 600. The electrode body 600 includes a body part 610 of the electrode body, and a tab part 620 projecting from the body part 610 of the electrode body and joined to a first direction side of the current collector 500. The electrode terminal 200 includes: a shaft part 201 penetrating through the wall part in a first direction; and a projecting portion 202 projecting from the shaft part 201 in a second direction intersecting the first direction, and disposed on the first direction side of the current collector 500 to sandwich the current collector 500 by the wall part and the projecting portion. The tab part 620 is disposed adjacent to the projecting portion 202 as viewed from the first direction, or disposed on the first direction side of the projecting portion 202.SELECTED DRAWING: Figure 4 【課題】省スペース化を図ることができる蓄電素子を提供する。【解決手段】容器１００と、電極端子２００と、電極体６００と、容器１００の壁部の第一方向側に配置されて電極端子２００及び電極体６００に接続される集電体５００と、を備える蓄電素子１０であって、電極体６００は、電極体本体部６１０と、電極体本体部６１０から突出し、集電体５００の第一方向側に接合されるタブ部６２０と、を有し、電極端子２００は、当該壁部を第一方向に貫通する軸部２０１と、軸部２０１から第一方向と交差する第二方向に突出し、かつ、集電体５００の第一方向側に配置されて当該壁部とで集電体５００を挟み込む突出部２０２と、を有し、タブ部６２０は、第一方向から見て突出部２０２と隣接して配置される、または、突出部２０２の第一方向側に配置される。【選択図】図４
