Provided is a heat conductive silicone grease composition, including: (A) 100 parts by volume of an organopolysiloxane of a specific structure with a kinematic viscosity at 25° C. within a range from 10 to 100,000 mm 2 /s, (B) 0.1 to 50 parts by volume of an organopolysiloxane that functions as a wetter and contains a triorganooxysilyl group bonded to one terminal via an alkylene group that may be branched, and (C) 100 to 2,500 parts by volume of a heat conductive filler. The composition exhibits high thermal conductivity, displays excellent initial fluidity and is capable of retaining that fluidity over an extended period, and exhibits excellent heat radiation performance. Heat generated by a heat-generating body can be dissipated into a heat-radiating body by sandwiching the composition between the heat-generating body and the heat-radiating body. |
