Abstract

To provide a multilayer structure that may adhere to rubber material without the necessity of providing an adhesive layer, an inner liner and a pneumatic tire using the multilayer structure. According to the present invention, a multilayer structureis formed by alternately laminating elastomer layerscontaining thermoplastic elastomer and barrier layerscontaining a gas barrier resin, wherein an outermost layerlaminated uppermost among layers constituting the multilayer structurecontains an elastomer component that may heat-adhere to diene rubber.
