Abstract: An adhesive for laminating a metal foil to a resin film, the adhesive including: a polyol (A); a multimer of a polyisocyanate (B); and a metal compound (C) being a compound of at least one metal of Groups 7 and 12, wherein the multimer of a polyisocyanate (B) contains a multimer of a saturated aliphatic polyisocyanate and a multimer of a saturated alicyclic polyisocyanate. Also disclosed is a laminate having a metal foil and a resin film laminated through an adhesive layer obtained from the adhesive for laminating of the invention. Yet further disclosed is a packaging material for a battery casing obtained by using the laminate. Yet further disclosed is a battery case obtained by using the packaging material for a battery casing. Also disclosed is a method for producing a battery case which includes deep drawing or bulging the packaging material for a battery casing.
