Abstract: A graphite sheet can be combined with a base even without the need for use of an adhesive. A surface layer porous graphite sheet includes: a graphite layer and a porous layer arranged on one or both surfaces of the graphite layer. The porous layer has pores having a pore diameter X that is measured on a surface of the porous layer and pores having a pore diameter Y that is measured inside the porous layer and that is larger than the pore diameter X. A porosity in a cross section of the surface layer porous graphite sheet satisfies a predetermined condition.

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.
