A rubber-metal laminated gasket material comprising a metal plate and fluororubber or nitrile rubber laminated on the metal plate, wherein an amorphous carbon film having a nanoindentation hardness on a silicon wafer of 10 GPa or more and a film thickness of 200 nm or more is formed on a rubber layer outer surface of the rubber-metal laminated gasket material by a plasma CVD method that supplies a high-frequency power from a high-frequency power source using unsaturated hydrocarbon gas. The rubber-metal laminated gasket material reduces the wear and abrasion of the gasket material due to friction with the seal mating surface under high temperature use.
