PROBLEM TO BE SOLVED: To provide an electrode body which can, at the time of pressure application for improving power storage performance, receive uniform surface pressure, while suppressing electrode displacement.SOLUTION: An electrode body has a laminated structure in which a positive electrode 11 and a negative electrode 12 are laminated with a separator 13 sandwiched therebetween. In a plan view, the separator 13 has portions 16 protruding from the positive electrode 11 and the negative electrode 12 on both sides, in a predetermined direction, of the positive electrode 11 and the negative electrode 12. The portions 16 overlap each other and are formed as opposing portions which face each other without sandwiching the positive electrode 11 and the negative electrode 12 therebetween. The opposing portions 16 are provided with an adhesive layer 17, and the adhesive layer 17 bonds the opposing portions 16 overlapping each other.SELECTED DRAWING: Figure 3 |
