PROBLEM TO BE SOLVED: To provide a power storage device which can prevent a tab from being split.SOLUTION: An electrode assembly 14 comprises a positive electrode housing unit 60 which is obtained by uniting a positive electrode 21, a first separator 23 covering one surface of the positive electrode 21, and a second separator 24 covering the other surface of the positive electrode 21. At one side part 21c of the positive electrode 21, a positive electrode tab 31 formed so as to project from the one side part 21c is provided. Here, a first corner part 91 is formed by the one side part 21c and a peripheral part 80 of the positive tab 31, and a second corner part 92 is formed on a tip side in a projection direction T from a first weld 61. |
