1. An antistatic silicone rubber composition comprising
(A) an organopolysiloxane having at least two silicon atom-bonded alkenyl groups per molecule;
(B) an organopolysiloxane having at least two silicon atom-bonded hydrogen atoms per molecule in an amount such that a content of silicon atom-bonded hydrogen atoms in this component is from about 0.1 to about 10 moles per 1 mole of silicon atom-bonded alkenyl groups in component (A);
(C) a hydrosilylation catalyst in a sufficient amount to cure the composition;
(D) at least one potassium salt selected from the group consisting of a potassium alkyl phosphate, potassium bis(trialkylsilyl)amide, potassium dialkyl amide, potassium phenoxide, and potassium permanganate, in an amount of from 0.1 to about 15 mass % of the composition; and
(E) a hydrolyzation reaction inhibitor in an amount of from about 0.001 to about 1 mass % of the composition.
