Provided is an accurate method for producing a carbon material in which a high purity carbon material having an extremely low concentration of ash can be economically obtained. The method for producing a carbon material that can be used as a nonferrous metal reducing agent, a structural-use carbon material, an electric material-use carbon material, or as a raw material in each, involves an ashless coal producing process for producing ashless coal, which is modified coal, by modifying coal with the use of a solvent, an ashless coal heating process for heating the ashless coal that was produced by the ashless coal producing process, and a carbonizing process for obtaining the carbon material by carbonizing the ashless coal that was heated by the ashless coal heating process. The ratio of the number of hydrogen atoms and carbon atoms (H/C) in the ashless coal that was heated by the ashless coal heating process is in the range of 0.6 to 0.67. |
