    Abstract: Provided is a heat conductive silicone grease composition including (A) 100 parts by mass of an organopolysiloxane containing 2 or more alkenyl groups bonded to silicon atoms within each molecule, (B) an organohydrogenpolysiloxane containing 2 or more hydrogen atoms bonded to silicon atoms within each molecule, in sufficient quantity to provide from 0.1 to 5.0 hydrogen atoms bonded to silicon atoms within the component (B) for each alkenyl group within the component (A), (C) 100 to 2,200 parts by mass of a heat conductive filler, (D) an effective quantity of a platinum-based catalyst, and (E) an effective quantity of an addition reaction retarder, in which the component (C) includes more than 90% by mass and no more than 100% by mass of an indium powder with an average particle size of 0.1 to 100 μm. Also provided is a heat conductive silicone cured product obtained by curing the above composition by heating at a temperature equal to, or greater than, the melting point of the indium powder. Further provided is an electronic device including an electronic component, a heat radiating member, and a heat conductive member including the above cured product disposed between the electronic component and the heat radiating member. Still further provided is a method of curing the above composition. Even further provided is a method of forming a heat conductive member between an electronic component and a heat radiating member. The above heat conductive silicone grease composition generates a suitably thin cured product with excellent thermal conductivity that prevents problems such as the contamination of components other than the coated component, and the leakage of oily materials from the product if used over extended periods.
