Provided is a silicone gel composition including (A) an organopolysiloxane containing at least one alkenyl group bonded to a silicon atom within each molecule, represented by an average composition formula: R<SUB>a</SUB>R<SUP>1</SUP><SUB>b</SUB>SiO<SUB>(4-a-b)/2 </SUB>(wherein, each R group represents, independently, an alkenyl group, each R<SUP>1 </SUP>group represents, independently, an unsubstituted or substituted monovalent hydrocarbon group that contains no aliphatic unsaturated bonds, a represents a positive number from 0.0001 to 0.2, b represents a positive number from 1.7 to 2.2, and a+b represents a number within a range from 1.9 to 2.4), (B) an organohydrogenpolysiloxane containing at least two hydrogen atoms bonded to silicon atoms within each molecule, and (C) a platinum-based catalyst. Also provided is the silicone gel composition stated above, in which a penetration value of a cured product of this composition, as defined in JIS K2220, is within a range from 20 to 200. The silicone gel composition generates a silicone gel cured product which displays a low elastic modulus and low stress, and suffers no oil bleeding over time.
