Higher adhesion has become required between the rubber vulcanizates of the inner rubber layer (APR layer) 1 and the outer rubber layer (hydrin rubber layer) 3, especially the inner rubber layer 1 and the reinforcing layer 5. When the outer rubber layer 3 is molded by a continuous molding method in which the outer rubber layer 3 is molded substantially simultaneously and continuously at the same location (see Japanese Patent Application Laid-Open No. 100161/1989, etc.), it is possible to mold the outer rubber layer 3 without using an adhesive. , it was necessary to integrate them only by vulcanization adhesion, and it was difficult to obtain a high degree of adhesion between the inner rubber layer and the outer rubber layer.
