PROBLEM TO BE SOLVED: To provide a silicone composition without bonding to a cured product of a material consisting essentially of a silicone even when used by building thereof on the cured product of the material consisting essentially of the silicone such as that used as a silicone impression material in the field of dental treatment. SOLUTION: The silicone composition is composed of (A) 100 pts.wt. of an organopolysiloxane having at least 2 aliphatic unsaturated hydrocarbons in one molecule, (B) 0. l-50 pts.wt. of an organohydrogenpolysiloxane having SiO<SB>2</SB>units and at least 3 hydrogen atoms directly bonded to a silicon atom in one molecule, (C) 0.1-50 pts.wt. of fine silica powder having 50-500 m<SP>2</SP>/g BET specific surface area and the surface subjected to a hydrophobization treatment and a silicone-soluble platinum compound in an amount of 10-800 ppm based on 100 pts.wt. of the sum total of the component (A) and the component (B).
