Abstract: A re-forming process is carried out in which a material graphite film is heat-treated to not less than 2000° C. while the material graphite film is being pressured. Through the re-forming process, sag of a graphite film is controlled. By using, during the re-forming process, a plurality of inner cores having respective different surface states, it is possible to produce a graphite film having two or more sag forms which have respective effects.

Abstract: A graphite film has a higher degree of thermal diffusion property in one in-plane direction and a method produces the graphite film. The graphite film includes a first axial direction, which is a direction having the highest thermal diffusivity in a film surface, and a second axial direction orthogonal to the first axial direction in the film surface. A value obtained by dividing the thermal diffusivity in the first axial direction by a thermal diffusivity in the second axial direction is not less than 1.020 and not more than 1.300.

Abstract: There has been a problem that wrinkles easily occur on a carbonaceous film produced by the use of a continuous production method and on a graphite film obtained by heat-treating the carbonaceous film. In the present invention, heating treatment is carried out on a polymeric film while applying pressure to the polymeric film in the film thickness direction with the use of a continuous carbonization apparatus. This makes it possible to obtain a carbonaceous film and a graphite film in which wrinkling is reduced.
