PROBLEM TO BE SOLVED: To provide a low-cost, easy-to-manufacture heat conductive sheet which is excellent in heat conductivity, electric insulation, flexibility and shape followability. SOLUTION: In a heat conductive sheet formed by molding a mixed composition obtained by blending a heat conductive filler with silicone rubber into a sheet, the average particle diameter is 50 as a heat conductive filler. Silicon carbide powder having an average particle size of 2 to 10 μm; and aluminum oxide powder of μm. It is preferable to further mix graphitized carbon fibers as the heat conductive filler, and the total amount of these heat conductive fillers is 60 to 7 It is preferably 0% by volume. |
