PROBLEM TO BE SOLVED: To obtain a rubber composition suppressing the elevation of its viscosity even an blending a large amount of carbon black, and capable of producing an electromagnetic wave shielding material and an electric conductive rubber part in a good processing property. SOLUTION: This rubber composition contains (a) 100 pts.wt. ethylene-α- olefin-based copolymer rubber, (b) 50-175 pts.wt. carbon black having 10-50 m2/g specific surface area and 100-150 ml/100 g DBP oil absorbing amount and (c) 1-50 pts.wt. carbon fiber.
