PROBLEM TO BE SOLVED: To provide an addition reaction-type solventless silicone composition having excellent thin film coatability and curability, exhibiting excellent releasing performance and giving a releasable cured silicone film generating little cissing of an emulsion-type adhesive. SOLUTION: The curable silicone releasing agent composition contains the following components (A) to (E), has a viscosity of 50-1,000 mPa s at 25°C and is free from organic solvent. (A) A diorganopolysiloxane having an alkenyl group bonded to a silicon atom at a molecular chain terminal; (B) a diorganopolysiloxane having hydrogen atom bonded to a silicon atom at the molecular chain terminal; (C) an organohydrogenpolysiloxane having at least 3 hydrogen atoms bonded to silicon atom in one molecule; (D) a resin copolymer composed of the units of general formula R<SB>3</SB>SiO<SB>1/2</SB>(M unit) and SiO<SB>4/2</SB>(Q unit); and (E) a platinum-group metal catalyst.
