PROBLEM TO BE SOLVED: To provide a power storage device capable of inhibiting a terminal from being rotated together.SOLUTION: A secondary battery 10 includes: a terminal 15 having a screw part; a positive electrode conductive member 40 joined to a positive electrode tab 31 and the terminal 15; and an insulation cover member 62 interposed between the terminal 15 and an electrode assembly 14. The insulation cover member 62 includes a non-circular base part 62a having a predetermined width in the lamination direction of the electrode assembly 14. The width of the base part 62a is set corresponding to a distance between facing inner surfaces so that rotation of the terminal 15 and the conductive member 40 is regulated by being abutted on the facing inner surfaces of the case 11.SELECTED DRAWING: Figure 3 |
