    摘要： Provided is a heat-conductive silicone composition, including: (A) 100 parts by volume of an organopolysiloxane having a specific structure, (B) 0.1 to 50 parts by volume of an organosilicon compound that functions as a wetter and contains a triorganooxysilyl group bonded to one terminal via an alkylene group that may be branched, (C) 100 to 2,500 parts by volume of a heat-conductive filler, and (D) an effective quantity of a curing agent. Also provided is a heat-conductive silicone cured product obtained by curing this composition. The heat-conductive silicone composition, even when filled with a large quantity of a heat-conductive filler in order to provide superior thermal conductivity, exhibits a minimal increase in viscosity or plasticity, and retains favorable handling properties and moldability. The heat-conductive silicone cured product exhibits excellent flexibility even when filled with a large quantity of a heat-conductive filler. Heat generated by a heat-generating electronic component can be dissipated into a heat-radiating component by sandwiching the cured product between the heat-generating electronic component and the heat-radiating component.
