The vessel is pressurized with an inert gas, such as gaseous N2, to a pressure of 1-5kg/cm , and the temperature is slowly raised to 350-500 deg.C at a rate of 10 deg.C/min or less. Then, the pressure within the hermetically sealed vessel is decreased to 20mmHg or less, and the pitch is maintained at the above- mentioned temp. for 30min or less for heat treatment thereof. Thus, there is obtd. the title pitch having a benzene insoluble of 60-95wt% and a mesophase carbonaceous content of 95-100wt% and having a high softening temp., e.g., 300-400 deg.C, in a yield as high as 50% or more.
