Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a composite graphite film which can be used in the movable part, bent part, etc, of an electronic instrument, can bear repeated bending, and is excellent in thermal conductivity. SOLUTION: The composite graphite film 1 includes a graphite film 10 and a protective film 20 including a thermoplastic resin-containing layer 20a stuck on at least one side of the graphite film 10. The graphite film 10 has a thickness of 400 μm or below, a tensile modulus of elasticity of at least 0.5 GPa, and a heat conductivity of at least 200 W m-1K-1. The protective film 20 has a thickness of 5-65 μm and a tensile modulus of elasticity of 1-4 GPa. COPYRIGHT: (C)2009,JPO&INPIT
