摘要： A non-aqueous electrolyte secondary battery having both high capacity and long-life is provided by solving the problem of the large irreversible capacity of a negative electrode active material. The non-aqueous electrolyte secondary battery is produced by a method including the steps of: reacting lithium with a negative electrode active material by bringing a metal film that is composed mainly of lithium into contact with a surface of a negative electrode active material layer; and thereafter combining the negative electrode with a positive electrode to form an electrode assembly. The metal film composed mainly of lithium is preferably formed on a carrier that does not chemically react with lithium, and the metal film on the carrier is preferably brought into contact with the negative electrode active material layer while heating and applying a pressure thereto.
