PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery with low cycle deterioration rate and high reliability. SOLUTION: In a nonaqueous electrolyte secondary battery in which a negative electrode 1 and a positive electrode 2 are oppositely arranged through a separator 3 and they are sealed in a battery can 5 through a sealing gasket 6, an active material layer having an active material holding binder is formed in at least either one of a negative current collector 10 and a positive current collector 11, and the active material holding binder is crosslinked by irradiating electron beams. The active material layer is formed on the surface of either one of the negative current collector 10 and the positive current collector 11, and electron beams of 10kGy or more but 700kGy or less are irradiated to the active material layer crosslinking the active material holding binder in the active material layer. |
