Abstract: Disclosed herein is a graphite composite material including a graphite film and a resin layer, wherein peeling-off of the resin layer from the graphite film is suppressed. The graphite composite material includes: a graphite film; and a resin layer formed on at least one surface of the graphite film, wherein the graphite film has through holes, wherein a number of the through is 100 to 1000 per cm2, and the through holes have a diameter of 0.10 mm or more but 1.00 mm or less, and wherein part of the resin layer is formed also in the through holes.

Abstract: In order to prevent positional displacement of a graphite sheet laminate during production of a resin molded product obtained by integrally molding the graphite sheet laminate and a resin, the present invention uses a graphite sheet laminate having a structure in which a first fixing layer having a modulus of elasticity of not less than 7.0×104 Pa and not more than 5.0×107 Pa at 250° C. is in contact with a graphite sheet on at least one of principal surfaces of the graphite sheet.

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.
