PROBLEM TO BE SOLVED: To provide an electrode lead wire member for a nonaqueous battery, which is increased in corrosion resistance so as to elongate a lithium ion battery life, and which is arranged to be able to avoid the adverse effect of hydrofluoric acid even when an electrolytic solution of a lithium ion battery reacts with water to produce hydrofluoric acid and thus increase the corrosion.SOLUTION: An electrode lead wire member 18 to be led out from a storage container for a nonaqueous battery comprises: a metal lead-out part 21; and a corrosion-resistant thin film coating layer 22 laminated on the surface of the lead-out part 21, which is made water resistant by crosslinkage of a resin having a skeleton of polyvinyl alcohol containing a hydroxyl group or a copolymer resin thereof is crosslinked. The thin film coating layer 22 includes a substance consisting of a metal fluoride or its derivative; the substance is capable of crosslinking the resin having a skeleton of polyvinyl alcohol containing a hydroxyl group or a copolymer resin thereof, which is included in the thin film coating layer 22.SELECTED DRAWING: Figure 4 |
