Abstract

A process for producing a graphite fiber is disclosed, which is characterized by using, as a starting material, an optically anisotropic pitch prepared from a compound having a specific chemical structure as represented by formula (I).
The resulting graphite fiber shows a highly developed graphite structure and has excellent electrical conductivity.
R : H, CH₃
m : integer of 1 or more.
