PROBLEM TO BE SOLVED: To obtain a silicone releasing agent composition having excellent coating performances for thin film, curability and adhesivity. SOLUTION: This curable silicone releasing agent composition comprises (A) an organopolysiloxane represented by the formula (R1R2SiO1/2)2+a(R2 SiO)n(RSiSO3/2)a (R1 is an alkenyl group; R is a mono-valent hydrocarbon group; 30<=n<=250; a is 0 or 1), having 50-1,000 mPa.s viscosity at 25 deg.C, (B) a diorganopolysiloxane represented by the formula (HR2SiO1/2)2(R2SiO)m (R is a mono-valent hydrocarbon group; 2<=m<=20), having 2-30 mPa.s viscosity at 25 deg.C (the molar ratio of hydrogen to R1 of (A) is 0.3-0.8), (C) an organohydrogenpolysiloxane containing at least three hydrogen atoms bonded to silicon atoms in one molecule (the molar ratio of hydrogen to R1 of (A) is 0.4-3.0) and (D) a platinum group metal-based catalyst as essential components, has 50-600 mPa.s viscosity at 25 deg.C and contains no organic solvent.
