PROBLEM TO BE SOLVED: To provide a power storage element that can reduce the electrical resistance between an electrode body and a current collector.SOLUTION: A power storage element 10 includes an electrode body 400, and a positive electrode current collector 120 and a negative electrode current collector 130 which are connected to the electrode body 400. The electrode body 400 has tab portions 411 and 421 which protrude outward and are connected to the positive electrode current collector 120 and the negative electrode current collector 130. The electric storage device 10 further includes electrically conductive materials 510 and 520 which are arranged in contact with the tab portions 411 and 421.SELECTED DRAWING: Figure 2 |
