Abstract
An electroconductive elastomer-forming composition comprising (a) 100 parts by weight of a vinyl group-containing polydimethylsiloxane having a standard polystyrene-reduced molecular weight of 10,000-40,000, (b) 5-50 parts by weight of a hydrosilyl group-containing polydimethylsiloxane having a standard polystyrene-reduced molecular weight of 10,000-40,000 and (c) 30-1,000 parts by weight of electroconductive particles. Said composition can form a conductor of small thickness having good conductivity, excellent heat resistance and excellent durability.
