[PROBLEMS] To prevent curling even if a silicone rubber composition is laminated only on one side of a heat-resistant resin film, curling is suppressed to be extremely small, excellent in handleability, and extremely resistant to damage even when repeated crimping at the same location. A thermally conductive silicone rubber composite sheet for thermocompression bonding having durability and a method for producing the same are provided. A heat conductive composite sheet for thermocompression bonding in which a silicone rubber layer made of a cured product of a silicone rubber composition is laminated on one side of a heat resistant resin film, and the total thickness of the composite sheet is 100 to 400 μm, the thickness ratio represented by the silicone rubber layer / heat resistant resin film is 2 to 10, the thickness of the heat resistant resin film is 20 to 50 μm, and ASTM D of the heat resistant resin film A thermally conductive composite sheet for thermocompression bonding having a tensile modulus of 4 to 20 GPa based on a -882 measurement method.
