PROBLEM TO BE SOLVED: To provide a nonaqueous battery with little deterioration of capacity in a charge and discharge cycle. SOLUTION: With the nonaqueous secondary battery having a sheet-form positive electrode and a sheet-form negative electrode placed face to face with a separator in between, the sheet-form negative electrode consists of a coating film containing at least a negative active material formed on a conductive base body, and as the binder for the sheet-form negative electrode, a bridging body of a carboxy-group containing polymer and a cross-linking material containing two or more epoxy groups capable of reacting with the above carboxy group is used. |
