Abstract
Disclosed herein are a process for producing a carbonaceous thin plate comprising PA0 disposing a composite material comprising a carbonaceous raw material which is carbonized and solidifies after being softened by heating and paper-like substances which are carbonized without melting between the pressing-surfaces of a heating press, so as to sandwich said carbonaceous raw material between said paper-like substances and to contact said paper-like substances with each of the pressing-surfaces of said heating press, PA0 press-molding said composite material by raising a temperature of said heating press PA0 continuously heating the thus press-molded composite material under a pressure, thereby carbonizing the thus press-molded composite material, and PA0 calcining the thus carbonized material under a reduced-pressure or in an inert gas.
