The present invention provides a laminate for use in a non-aqueous battery exterior and capable of increasing the mechanical strength of a laminate for use in a non-aqueous battery exterior, reducing the occurrence of defects during drawing, and improving non-aqueous battery production efficiency. More specifically, the present invention provides a laminate 10 for use in a battery exterior and obtained by layering an SUS foil 12 and a sealant layer 13. At least the sealant layer 13 side of the SUS foil 12 has a surface-covering layer 17 having a thickness of 0.05-1.0μm formed thereon by drying and curing a water-soluble coating material containing a water-soluble resin and a metal fluoride compound. The surface of the SUS foil 12 on the side thereof opposite the sealant layer 13 has a coating layer 16 formed thereon from at least one or more types of resin selected from a resin group consisting of a urethane resin, an acrylic resin, polyvinylidene chloride, a vinylidene chloride-vinyl chloride copolymer resin, a maleic anhydride-modified polypropylene resin, a polyester resin, an epoxy resin, a phenolic resin, a phenoxy resin, a fluorine resin, a cellulose ester resin, a cellulose ether resin, a polyamide resin, PPE, PPS, PAE, and PEEK. |
