Claim:
A rubber composition comprising: an ethylene/α-olefin/non-conjugated polyene copolymer [A] satisfying the following (a) to (f): (a) the copolymer [A] is a copolymer of ethylene, an α-olefin and a non-conjugated polyene, (b) the number of carbon atoms of the α-olefin is in the range of 3 to 20, (c) the ethylene unit/α-olefin unit weight ratio is in the range of 35/65 to 95/5, (d) the iodine value is in the range of 0.5 to 50, (e) the intrinsic viscosity [η], as measured in a decalin solution at 135° C., is in the range of 0.01 to 5.0 dl/g, and (f) the non-conjugated polyene is at least one norbornene compound represented by the following formula [I]: wherein n is an integer of 0 to 10, R 1 is a hydrogen atom or an alkyl group of 1 to 10 carbon atoms, and R 2 is a hydrogen atom or an alkyl group of 1 to 5 carbon atoms, and a SiH group-containing compound [C] which has two SiH groups in one molecule and is represented by the following formula [III]
