A thermally conductive silicone heat dissipating material contains a silicone polymer, a thermally conductive inorganic filler, and a heat resistance improver. The thermally conductive inorganic filler has a BET specific surface area (A.sub.BET) of 0.3 m.sup.2/g or more and is surface treated with a surface treatment agent expressed by Si(OR′).sub.4 or R.sub.xSi(OR′).sub.4−x (where R represents a hydrocarbon group having 1 to 4 carbon atoms or an aromatic hydrocarbon group having 6 to 12 carbon atoms, R′ represents a hydrocarbon group having 1 to 4 carbon atoms, and x represents an integer of 1 to 2). The content of the thermally conductive inorganic filler is 100 to 10000 parts by mass with respect to 100 parts by mass of the silicone polymer. The thermally conductive inorganic filler having a large specific surface area and a small average particle size is surface treated with a silane coupling agent with a low molecular weight, so that the heat resistance of the thermally conductive silicone heat dissipating material is improved.
