Thermally conductive composite sheets and manufacturing method thereof
 Thermally conductive composite sheets which comprise a silicone rubber layer which contains thermally conductive fillers and has an Asker C hardness from 5 to 50, and a porous reinforcing material layer which has pores of at least 0.3 mm in diameter and is incorporated within the silicone rubber layer. The thermally conductive composite sheets of the present invention are superior in thermal conductivity and flexibility (for contact towards the electronic parts and so on) and are suitable for mass production and for the assembly process of electronic instruments. Therefore, utilization of the thermally conductive composite sheets enables the effective production of electronic instruments wherein performance degradation caused by heat hardly occurs.
