A thermally conductive silicone grease composition comprising at least the following components: (A) an organopolysiloxane which is liquid at 25° C. and is represented by the following average compositional formula: R1aSiO(4-a)/2, where, R1 is a monovalent hydrocarbon group; and "a" is a number ranging from 1.8 to 2.2; (B) a thermally conductive filler composed of constituents (B1) to (B3) given below, wherein: constituent (B1) is spherical aluminum oxide powder with an average particle diameter ranging from 15 to 55 mum; constituent (B2) is spherical aluminum oxide powder with an average particle diameter ranging from 2 to 10 mum; constituent (B3) is aluminum oxide powder with an average particle size not exceeding 1 mum; and (C) an alkoxysilyl-containing organopolysiloxane. The composition, along with high thermal conductivity, possesses excellent handleability and low coefficient of friction.
