MULTI-LAYER STRUCTURE, INNER LINER FOR PNEUMATIC TIRE, AND PNEUMATIC TIRE

To provide a multilayer structure having high gas barrier property and crack resistance as well as excellent fatigue resistance, an inner liner for a pneumatic tire using such a multilayer structure, and a pneumatic tire comprising the inner liner. According to the present invention, in a multilayer structure 1 including a barrier layer 2 and an elastomer layer 3, a proportion of a thickness of the elastomer layer 3 in the multilayer structure ((U1+U2+...+Un)/T) is 60% or more.
