Summary:To provide a silicone impression material having high viscosity of a kneaded material before curing and low hardness after curing. A dental silicone impression material composition includes: A) an organopolysiloxane mixture comprising a) an organopolysiloxane having at least two aliphatic unsaturated hydrocarbons in one molecule and having viscosity of 1,000,000 mPa·s or more at 25° C., and b) an organopolysiloxane having at least one aliphatic unsaturated hydrocarbon in one molecule and having viscosity of 100 to 5,000 mPa·s at 25° C., wherein a ratio of a):b) is 1:0.5 to 10; B) an organohydrogenpolysiloxane having at least three hydrogen atoms directly bonded to a silicon atom in one molecule; C) a silicone-soluble platinum compound; D) an organopolysiloxane not having a functional group; and E) an inorganic filler.
