<P>PROBLEM TO BE SOLVED: To provide a silicone self-adhesive composition and a silicone self-adhesive tape using it. Ž<P>SOLUTION: The silicone self-adhesive composition is an addition reaction-curing type silicone self-adhesive composition comprising (A) a linear polysiloxane having two or more alkenyl groups in one molecule and exhibiting viscosity of ≥10,000 mPa s at 25°C, (B) a polysiloxane comprising an R<SP>1</SP><SB>3</SB>SiO<SB>0.5</SB>unit and an SiO<SB>2</SB>unit at a molar ratio, which is a molar ratio of the R<SP>1</SP><SB>3</SB>SiO<SB>0.5</SB>unit to the SiO<SB>2</SB>unit, of 0.6-1.7 (R<SP>1</SP>is a 1-10C monovalent hydrocarbon group), (C) a polysiloxane having two or alkenyl groups in one molecule and exhibiting viscosity of 20-500 mPa s at 25°C, (D) a polysiloxane containing two or more SiH groups in one molecule, (E) a reaction controlling agent, and (F) a platinum catalyst. The self-adhesive tape has a plastic film and a cured product layer of the silicone self-adhesive composition laminated to at least one surface of the plastic film. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
