PROBLEM TO BE SOLVED: To provide a laminate capable of maintaining high gas barrier properties even when curving is repeatedly imparted without using an aluminum foil in the laminate. SOLUTION: The laminate comprises a base layer 1, a vapor-deposited thin film layer 2 of an inorganic oxide, an adhesive layer 3, and a gas barrier sealant layer 4, sequentially laminated. In this case, the sealant layer 4 has a laminate constitution of a metal vapor-deposited thin film layer 4a, an intermediate resin layer 4b and a heat sealable resin layer 4c. The layer 4a is made of a metal aluminum, and the layer 4b is made of a polypropylene resin.
