A silicone rubber composition for sealing a stitched air bag, wherein the composition exhibits excellent adhesion to cured silicone rubber. A silicone rubber composition for sealing a stitched air bag, in which the composition is used as a sealing material at those sections of a silicone rubber-treated base fabric that are superimposed with the treated surfaces facing each other and then stitched together to form a bag shape during formation of the air bag, and comprises: (A) an organopolysiloxane containing at least two alkenyl groups bonded to silicon atoms within each molecule, (B) a straight-chain organohydrogenpolysiloxane containing SiH groups only at the molecular chain terminals, (C) an organohydrogenpolysiloxane containing at least three SiH groups within each molecule, (D) a finely powdered silica, and (E) a platinum group metal-based catalyst, wherein the total quantity of all SiH groups within the components (B) and (C) is within a range from 0.01 to 20 groups per alkenyl group bonded to a silicon atom within the composition, and the number of SiH groups within the component (C) represents from 5 to 98 mol % of the total number of all SiH groups within the components (B) and (C).
