With respect to a laminate of a film formed of a thermoplastic resin or thermoplastic elastomer composition and a layer formed of a rubber composition in which an epoxidized natural rubber is blended, the adhesion between the film and the layer of the rubber composition is improved without using a large amount of the epoxidized natural rubber. A laminate of a film formed of a thermoplastic resin or thermoplastic elastomer composition and a layer formed of a rubber composition, said laminate being characterized in that: 5-60% by mass of a rubber component contained in the rubber composition is composed of an epoxidized natural rubber and 20-50% by mass of the rubber component is composed of a butadiene rubber; and the rubber composition contains an unsubstituted or substituted aromatic carboxylic acid having a pKa of 1.5-4.0 in an amount of 0.5-5 parts by mass per 100 parts by mass of the rubber component.
