Abstract

A multilayered structure having a layer A constituted with a resin composition containing a gas barrier resin, and a layer B being adjacent to the layer A and being constituted with a resin composition containing an elastomer. The total number of the layer A and the layer B is at least 7. The average thickness of the layer A in terms of a single layer is no less than 0.001 μm and no greater than 10 μm, and the average thickness of the layer B in terms of a single layer is no less than 0.001 μm and no greater than 40 μm. The multilayered structure is formed by irradiating with an active energy ray. Furthermore, an inner liner having the multilayered structure, and a pneumatic tire provided with the inner liner are provided.
