  "textContent": "Disclosed is an inner liner for a pneumatic tire, the inner liner including no less than 8 resin-layers, the resin-layer having a layer A constituted with a resin composition containing a gas barrier resin, and a layer B constituted with a resin composition containing an elastomer, at least one of the resin compositions included in the layer A and the layer B that are adjacent with each other containing a metal salt, the content of the metal salt being no less than 1 ppm and no greater than 10,000 ppm in terms of metal element equivalent, and an interlayer adhesive force between the layer A and the layer B being no less than 500 g/15 mm. The layer A and the layer B are preferably alternately laminated. The average thickness of single layer of the layer A and the layer B is preferably no less than 0.01 µm and no greater than 10 µm. The multilayered structure has a thickness of preferably no less than 0.1 µm and no greater than 1,000 µm. As the metal salt, at least one selected from the group consisting of alkali metal salts, alkaline earth metal salts and d-block metal salts in group 4 are preferably used.",
