PROBLEM TO BE SOLVED: To provide a power storage device in which tub groups can be installed suitably while superimposing respective tubs suitably.SOLUTION: A secondary battery 10 includes an electrode assembly 14 formed in layer by superimposing electrodes 21, 22 while sandwiching a separator 23. At the end of the positive electrode 21, a positive electrode tub 31 not coated with an active material is formed to project from the end, and the positive electrode tubs 31 are superimposed to constitute a positive electrode tub group 41. A positive electrode conductive member 61 having the facing parts 81, 82, sandwiching the extension 72 of the positive electrode tub group 41, is provided. The extension 72 is bent along the shape of each waveform parts 81b, 82b of each facing part 81, 82. |
