PROBLEM TO BE SOLVED: To suppress a decrease in energy density by improving insertability into a case.SOLUTION: Separators 21a and 21b sandwiching a positive electrode 19 are joined to a negative electrode 20 adjacent to the positive electrode 19 in a state in which the positive and negative electrodes 19 and 20 are stacked. Specifically, an adhesive is applied to a gap D between each protruding part 30b of the separators 21a and 21b and the negative electrode 20, and the separators are joined to the negative electrode by an adhesive joint part 32 made of the adhesive. |
