Claim:
1. A method for producing graphite, comprising the steps of: introducing graphitizable material particulates having an average particle diameter of 3 to 30 mm into an inside of a vertical graphitization furnace from an upper part thereof, heating the graphitizable material particulates at 2200° C. to 3200° C. while making inert gas flow from a lower part toward an upper part thereof to graphitize the graphitizable material particulates, and removing obtained graphite through a lower part thereof, wherein the graphitizable material particulates are obtained by granulating a mixture comprising 100 parts by weight of graphitizable carbonaceous substance powder having an average particle diameter of 10 to 20 μm, 3 to 20 parts by weight of a binder evaporable or evaporable through decomposition at a temperature of lower than 1000° C., and 5 to 30 parts by weight of a solvent or a dispersant which can dissolve or disperse the binder.
