PROBLEM TO BE SOLVED : To provide a heat-resistant silicone rubber composition having transparency and giving silicone rubber with heat resistance being improved so that rubber elasticity is not damaged under the environment at 300°C or more.SOLUTION : The heat-resistant silicone rubber composition contains (A) a linear organopolysiloxane represented by the formula (1), (B) an organohydrogenpolysiloxane being represented by the formula (2) and having two or more silicon atom-bonded hydrogen atoms in one molecule, and (C) a platinum group metal-based catalyst. [R is a monovalent hydrocarbon group, m≥0 and n≥0. A is an organic functional group represented by the formula.] (R, Rand Rare each a hydrogen atom or a monovalent hydrocarbon group.) RHSiO(2), (Ris a monovalent hydrocarbon group comprising no aliphatic unsaturated bond, 0.7≤a≤2.1, 0.001≤b≤1.0 and 0.8≤a+b≤3.0.)
