PROBLEM TO BE SOLVED: To provide a heat-curable silicone rubber adhesive composition maintaining curing stability after storage, providing a cured product having good heat-stability, and having good adhesion even to a resin with poor adhesion. SOLUTION: The heat-curable silicone rubber adhesive composition comprises (A) an organopolysiloxane having two or more alkenyl groups bound to a silicon atom in one molecule represented by the formula: R<SP>1</SP><SB>a</SB>R<SP>2</SP><SB>b</SB>SiO<SB>(4-a-b)/2</SB>(wherein R<SP>1</SP>denotes a monovalent hydrocarbon group; R<SP>2</SP>denotes an alkenyl group; a is 0.96-2.00; b is 0.001-0.5; and a+b=1.00-2.04), (B) an organohydrogenpolysiloxane represented by the formula: R<SP>3</SP><SB>c</SB>H<SB>d</SB>SiO<SB>(4-c-d)/2</SB>(R<SP>3</SP>is the same as R<SP>1</SP>; c is 0.70-2.0; d is 0.01-1.2; and c+d=0.8-3.0), (C) a platinum metal compound, (D) a curing controlling agent, (E) an addition-curable functional group-containing alkoxysilane, an organosiloxane containing an addition-curable functional group and an alkoxy group, or an isocyanurate compound containing an addition-curable functional group and an alkoxysilyl group, (F) a zirconium compound, and (G) a carboxylic acid anhydride.
