An object of the present invention is to provide a graphite film and a manufacturing method thereof, and a graphite film both having an excellent thermal diffusivity which can sufficiently manage heat dissipation of electronic instruments, precision instruments and the like, along with an excellent flex resistance which can withstand application to bent portions. The manufacturing method thereof is a graphite film manufacturing method of graphitization of raw material film formed by polymeric films and/or carbonized polymeric films. The maximum temperature of graphitization is 2,800[deg.] C. The pressure applied to the source material film in the thickness direction in the present invention may be not less than 5.0 g/cm<2>, and more preferably not greater than 100 g/cm<2>. The number of the laminated pieces is not less than 10. |
