PROBLEM TO BE SOLVED: To improve a charge/discharge cycle life by increasing adhesion between a positive/negative electrode layer and a collector in the case of using a metal sheet as the collector. SOLUTION: This cell comprises a positive electrode having a structure supporting an active material, nonaqueous electrolyte and a positive electrode layer 2 containing a polymer holding this electrolyte to a metal sheet as a collector 1, negative electrode having a structure supporting an active material, nonaqueous electrolyte and a negative electrode layer 4 containing a polymer holding this electrolyte to a collector 3, nonaqueous electrolyte interposed between the positive/negative electrode layers and a solid polymer electrolyte layer 5 containing a polymer holding this electrolyte. Here, the positive electrode layer 2 has a carboxyl group, and a polymer of nonaqueous electrolyte resistance is contained. |
