PROBLEM TO BE SOLVED: To provide a method for producing an aging resistant rubber material, capable of improving heat resistance without damaging molding property even on forming the rubber layer by using an aqueous latex of the rubber, and not suffering from its increased cost even on performing an adhesion-preventing treatment with an adhesion-preventing agent. SOLUTION: This method for producing the aging resistant rubber material is provided by applying an applying liquid obtained by dissolving or dispersing an amine-based anti-aging agent on the surface of a cross-linked rubber material, and then diffusing the amine-based anti-aging agent into the rubber material by heating at≥80°C temperature. In the case of using an applying liquid obtained by dissolving or dispersing the adhesion-preventing agent together with the amine-based anti-aging agent, the adhesion-preventing treatment of the cross-linked rubber material as a product is performed at the same time.
