摘要 Solid carbon material having extremely high flexural strength can be produced by introducing a sufficient amount of functional group to satisfy the undernoted general equation into a pitch having a H/C atomic ratio of 0.8 at most, thereby obtaining precursory carbon material; shaping said precursory carbon material into a desired article without using any binding material; and carbonizing or further graphitizing said article; wherein the general equation is <IMAGE> where, H/C is the hydrogen-to-carbon atomic ratio of the pitch, R is a numeral ranging from 0.2 to 0.3, and f is the percent by weight of at least one of oxygen, sulfur and halogen contained in the total functional groups introduced into the precursory carbon material on the basis of the weight thereof.
