PROBLEM TO BE SOLVED: To obtain a rubber composition that has fatigue resistance, mechanical characteristics and dynamic characteristics which are equal to those of a diene- based rubber such as natural rubber, and at the same time, is excellent in heat resistance and weather resistance. SOLUTION: The rubber composition comprises (A) an ethylene/3-20Cα-olefin/ non-conjugated polyene copolymer, (B) a fine powdered silicic acid and/or a fine powdered silicate each having a specific surface area of 5-500 m<2> /g (BET adsorption: ISO 5794/1, Annex D), (C) at least one metal salt of anα,β-unsaturated carboxylic acid, (D) an organic peroxide, and if necessary, further comprises (E) at least one antiaging agent selected from a sulfur type antiaging agent, a phenol type antiaging agent and an amine type antiaging agent and/or (F) a composition comprising sulfur. The rubber product is produced by crosslinking the rubber composition.
