Disclosure of Invention An object of the present invention is to provide a graphite film and a graphite composite film having both excellent thermal diffusivity that can sufficiently solve heat dissipation of electronic devices, precision devices, and the like and excellent bend resistance that can withstand use in a bent portion. In the MIT bending test, the solution of the present invention uses a rectangular test piece having a width of 15 mm, and the bending radius of curvature R is 2 mm, the bending angle 135 degrees at the left and right, the bending speed is 90 times / min, and the load is 0.98 N. It is a graphite film whose frequency of reciprocation bending until cutting measured on conditions is 10000 or more times. |
