A conductive silicone rubber composition is provided, which includes (a) 100 parts by weight of an organopolysiloxane represented by an average composition formula of RaSiO(4−a)/2 wherein R is an unsubstituted or substituted monovalent hydrocarbon group which may be the same or different, and a is a positive number of 1.90 to 2.05, (b) 50 to 500 parts by weight of conductive particles comprising carbon coated with Ni, and (c) 0.1 to 10 parts by weight of an organic peroxide. This composition has an adequate pot life, is unlikely to be affected by catalyst poisoning, and is suitable for normal pressure hot air vulcanization. Cured products produced from the composition has a low volume resistivity and excellent electromagnetic interference sealing properties.
