To provide a laminate which has excellent lamination strength, keeps the lamination strength between a vapor deposition thin film layer and a sealant layer even if various strongly permeable contents containing volatile substances operate, and has high gas-barrier properties.

At least an adhesion layer and the sealant layer are provided in this order on the vapor deposition thin film layer of a laminated base material in which the vapor deposition thin film layer formed of an inorganic oxide is provided on at least one side of the plastic base. The adhesion layer uses the laminate formed of an adhesion layer composing material added with polydimethylsiloxane compound of 0.01-0.5 mass% to a composition in which the mixing ratio of an isocyanate compound having a bi- or more-functional isocyanate group to a metal alkoxide is 99:1-60:40 (mass ratio).
