ABSTRACT:
A graphitized fiber heat-treated at a temperature higher than 2300.degree. C. in an inert atmosphere, of which oxidation weight reduction rate A in dry air at 650.degree. C. is in the range defined by the equation (1), of which BET specific surface area S determine by nitrogen or krypton adsorption technique at -196.degree. C. is in the range defined by the equation (2), and of which pore volume determined by the carbon dioxide adsorption technique at 25.degree. C. is 0.001 ml/g or less: ##EQU1## where, A is the oxidation weight reduction rate in dry air at 650.degree. C. in min.sup.-1
