To provide a silicone rubber adhesive composition which can simply integrally be molded with a thermoplastic resin in a short time by an injection molding method, is suitable for primer-less molding processes, has good adhesivity to the thermoplastic resin, can be adhered to the thermoplastic resin to give the integrally molded article without modifying the thermoplastic resin, and is useful for electric machines, electronic machines, automobiles, precision machines, construction-related articles, and so on.

This silicone rubber adhesive composition characterized by comprising (A) 100 pts.wt. of a thermosetting organopolysiloxane composition, (B) 1 to 100 pts.wt. of reinforcing silica fine powder, (C) 0.1 to 50 pts.wt. of an adhesivity-imparting component, and (D) 0.05 to 20 pts.wt. of a compound having at least one ester group in the molecule.
