Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an electricity storage device capable of suppressing an electrode from moving in a bag-shaped separator.SOLUTION: In a secondary battery, a positive electrode 12 is received in a bag-shaped separator 20. The positive electrode 12 includes a collector tab 16 having a shape projecting from a first side 12a and a positioning tab 17 having a shape projecting from a second side 12b. The bag-shaped separator 20 includes a first welded portion 25 welding a position sandwiching the collector tab 16 along the first side 12a and a second welded portion 26 welding a position sandwiching the positioning tab 17 along the second side 12b.SELECTED DRAWING: Figure 3 【課題】袋状セパレータ内での電極の移動を抑制することができる蓄電装置を提供すること。【解決手段】二次電池において、袋状セパレータ２０には正極電極１２が収納されている。正極電極１２は、第１の辺１２ａから突出した形状の集電タブ１６と、第２の辺１２ｂから突出した形状の位置決めタブ１７を備える。袋状セパレータ２０は、第１の辺１２ａに沿って集電タブ１６を挟む位置を溶着した第１溶着部２５を備えるとともに、第２の辺１２ｂに沿って位置決めタブ１７を挟む位置を溶着した第２溶着部２６を備える。【選択図】図３
