Abstract

A porous carbon material having excellent graphite crystallinity, good carrier mobility and proper porosity, a porous carbon material having edges of carbon hexagonal planes located on outer surfaces of particle and structure, and flaky graphite being similar to graphene are produced. By subjecting a carbon material, in which a closed-pore-ratio and an amount of remaining hydrogen in the material are set to be within a proper range, to hot isostatic pressing treatment, a vapor phase growth reaction of graphite is generated in closed pores as nuclei using hydrogen and hydrocarbon generated from the carbon material, thereby producing a large amount of targeted porous carbon material at low cost. Flaky graphite being similar to graphene is produced by applying physical impact to the obtained porous carbon material or by generating a graphite intercalation compound using the porous carbon material as a host and then quickly heating the compound.
