させることが困難となる。This gas atmosphere system is introduced into a reaction chamber provided in a heating area of, for example, an electric furnace, and is brought into contact with the surface of a clean graphite substrate placed therein. In this state, hydrocarbons undergo a rapid thermal decomposition reaction, and are precipitated on the graphite substrate as fibrous pyrolytic carbon with special properties under the catalytic action of 5iSz and H2S.9 [Operation] Given the above conditions, In hydrocarbons, scale-like carbonaceous substances are directly generated in the atmospheric space in the heterogeneous nucleation region prior to the formation of SiC and carbon whiskers due to the action of low partial pressure, and then due to the catalytic action of SiSz and H2S. It is deposited on a graphite substrate as a unique fibrous aggregate form. In this case, it is important that the catalyst substance be present as an atmosphere, and if it is attached to the graphite substrate surface, it will be difficult to produce the fibrous pyrolytic carbon of the present invention with a good yield.
