PROBLEM TO BE SOLVED: To provide a heat-resistant addition reaction-curable silicone adhesive capable of maintaining stable rubber physical properties and adhesiveness for a long period of time even if it is subjected to a heat test. SOLUTION: The heat-resistant silicone adhesive comprises (A) a diorganopolysiloxane having at least two alkenyl groups in a molecule, (B) an organohydrogenpolysiloxane having at least two hydrogen atoms in a molecule which are coupled to silicon atoms, (C) a hydrosilylation reaction catalyst, (D) a heat-resistance enhancer, and (E) as an adhesion-imparting component, a linear or branched organohydrogenpolysiloxane having at least one hydrogen atom in a molecule which is coupled to silicon atoms, wherein the molecular chain terminal of the organohydrogenpolysiloxane is alkoxylated or the silicon atom at the molecular chain terminal or in the molecular chain has an alkoxysilyl group via a carbon atom.
