Abstract
A thermal conductive composite silicone rubber sheet includes a thermal conductive silicone rubber sheet and a thermosoftening silicone resin layer with a thickness of 0.5 to 10 μm on one side of the thermal conductive silicone rubber sheet, the thermosoftening silicone resin layer having an viscosity at 70° C. of 700 Pa·s or lower, where the thermosoftening silicone resin layer has adhesion of 0.5 N/25 mm or higher at a normal temperature and the thermal conductive composite silicone rubber sheet has a thermal resistance lower than a value obtained by adding 0.3 cm2·K/W per one layer of one side of the thermosoftening silicone resin layer to a thermal resistance of the thermal conductive silicone rubber sheet. A thermal conductive composite silicone rubber sheet provided with an adhesive layer on one side of a thermal conductive silicone rubber sheet, makes it possible to impart adhesion without sacrificing thermal conductivity.
