PROBLEM TO BE SOLVED: To provide a rubber lamination body in which solubility of adhesive rubber is optimized, permeability of cement to a hydrogenated NBR rubber composition surface, and tackiness shortage of the hydrogenated NBR rubber composition is improved to improve moldability and adhesiveness. SOLUTION: The rubber lamination body is formed by adhering the hydrogenated NBR rubber composition A to sulfur vulcanizing diene rubber composition B through adhesive rubber composition C. Cement formed by adding 500-2000 pts.wt. mixed solvent containing 30-70 wt.% of at least one kind of organic solvent with Sp value 7.0-9.0 and 70-30 wt.% of at least one kind of organic solvent with Sp value 9.0-10.0 to 100 pts.wt. adhesive rubber composition C is applied to the surface of the rubber composition surface A, and then the adhesive rubber composition C is laminated to form the rubber lamination body.
