A thermally conductive silicone composition contains a silicone polymer and a thermally conductive inorganic filler. The thermally conductive inorganic filler is surface treated with a first surface treatment agent and further surface treated with a second surface treatment agent. The first surface treatment agent contains an organic silane compound represented by R.sup.11SiR.sup.12.sub.x(OR.sup.13).sub.3-x (where R.sup.11 is, e.g., a monovalent aliphatic hydrocarbon group having 1 to 18 carbon atoms, a monovalent aromatic hydrocarbon group having 6 to 30 carbon atoms, or a hydrocarbon group having an alkoxysilyl group, R.sup.12 is, e.g., a methyl group, and R.sup.13 is, e.g., a hydrocarbon group having 1 to 4 carbon atoms). The second surface treatment agent contains a silicone polymer that has a kinematic viscosity of 10 to 1000 mm.sup.2/s and does not have a hydrolyzable group. Thus, the present invention provides a thermally conductive silicone composition that has a low slurry viscosity and achieves high extrudability and high moldability, and a method for producing the thermally conductive silicone composition.
