Abstract
A thermally conductive sheet comprising a metal foil of which at least one side is coated with a graphite powder-containing silicone rubber layer to gain improved thermally conductive efficiency without attended by decrease in thermal conductivity with time and increase in production cost, and further to enable the enhancement of adhesiveness to other materials by easy incorporation of organopolysiloxanes of adhesion-conferring type into the silicone rubber layer, thus showing excellent aptitude for a thermally conductive sheet of full pack mold transistors.
