The present invention relates to an electrode lead wire member (18) which is led out from a container for nonaqueous batteries, said container being obtained using, as an outer package material, a film laminate that is composed of an aluminum foil and a resin film. This electrode lead wire member (18) comprises a lead-out part (21) that is formed of a metal. A thin film coating layer (22), which is formed from a metal fluoride or a derivative thereof and a resin containing a hydroxyl group or a copolymerized resin thereof, and a sealant layer (23) are sequentially laminated on the lead-out part (21). The sealant layer (23) is thermally bonded onto the surface of the lead-out part (21), and contains a thermally bondable polyolefin resin having an epoxy functional group at least in a portion that is on the side of the interface between the sealant layer (23) and the lead-out part (21). |
