摘要: A graphite plate has a surface roughness Ra from 10 μm to less than 40 μm and a surface-unevenness variation of 0.01% to 0.135% in any span 80 mm long within the surface of the graphite plate. A method for producing a graphite plate, includes r subjecting a polymer film to a heat treatment in an inert gas, wherein the heat treatment is conducted at 2400° C. to 3200° C., and a pressure of 10 kg/cm2 to 100 kg/cm2 is applied to the polymer film at 200° C. or higher.
