A curable silicone gel composition that is of low viscosity, exhibits good fluidity, and generates a silicone gel that exhibits good resistance to external stress and thermal stress. The composition includes (A) a specific organopolysiloxane having at least two alkenyl groups within each molecule, (B) an organohydrogenpolysiloxane having a specific branched main chain structure, containing at least three SiH groups within each molecule, and also containing at least one branch-forming unit within each molecule, and (C) a platinum-based catalyst, wherein the cured product has a penetration value of 10 to 200, and loss coefficient values at 25° C. for shear frequency values of 1 Hz and 10 Hz of 0.1 to 1.0 and 0.3 to 1.5 respectively. |
