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 structure 1 is formed by alternately laminating elastomer layers 3 containing thermoplastic elastomer and barrier layers 2 containing a gas barrier resin, wherein an outermost layer 4 laminated uppermost among layers constituting the multilayer structure 1 contains an elastomer component that may heat-adhere to diene rubber.
