Process for producing rubber-based composite material
 A process for producing a rubber-based composite material including steps of laminating a rubber compound onto a substrate, with a bonding layer of metal or metal compound interposed therebetween, and subsequently vulcanizing the rubber compound, characterized in that a prime-coating film is interposed between the substrate and the bonding film of metal or metal compound. The rubber-based composite material retains good bond strength even when used in such a way that its bond interface is in contact with water. In addition, it has good adhesion to the substrate treated by conversion treatment.
