PROBLEM TO BE SOLVED: To provide an electrode lead wire member for a nonaqueous battery that improves the corrosion resistance so as to avoid negative effects of corrosiveness increase, caused by hydrofluoric acid generated by reacting an electrolytic solution of a lithium ion battery with moisture, and extend the life of the lithium ion battery.SOLUTION: An electrode lead wire member 18 is led out from a housing container for a nonaqueous battery which is formed using a laminate film laminated body, composed of an aluminum foil and a resin film, as a sheath material. On an outer surface of a metal flat plate 21 having a strip shape, a polyvinyl alcohol resin or a polyvinyl ether resin and a protection layer 22 formed by applying and drying a solution containing a fluorine compound are formed. The fluorine compound is water soluble and the protection layer 22 is formed into a belt-like pattern by printing on the outer surface of the metal flat plate 21. |
