Abstract
An electroconductive silicone rubber having a high electroconductivity and retaining the good workability in compounding and molding and excellent properties inherent in silicone rubbers in general can be obtained by compounding a curable organopolysiloxane composition comprising a gum-like diorganopolysiloxane, carbon black as a conductivity-imparting agent and a curing agent with a cured silicone rubber powder of spherical particle configuration having specified particle diameter and specified sphericity which partially replaces the diorganopolysiloxane gum.
