Provided is an addition-curable silicone rubber composition for airbags. An addition-curable silicone rubber composition which contains:100 parts by mass of (A) an organopolysiloxane that contains two or more alkenyl groups in each molecule;(B) a cyclic organohydrogenpolysiloxane represented by formula (1),wherein the polysiloxane content is 50 mol% or more relative to the total amount of the component (B) when m = 2;(C) an organohydrogenpolysiloxane represented by formula (2), RHSiO (2)which contains two or more silicon atom-bonded hydrogen atoms in each molecule, in such an amount that the number of silicon atom-bonded hydrogen atoms in the components (B) and (C) is 1 to 7 per one silicon atom-bonded alkenyl group in the component (A) and the number of silicon atom-bonded hydrogen atoms in the component (B) is 1-30% of the number of silicon atom-bonded hydrogen atoms in the components (B) and (C);0.1-50 parts by mass of (D) a fine silica powder having a BET specific surface area of 50 m/g or more; andan effective amount of (E) an addition reaction catalyst.
