Abstract
A method for producing graphite fiber comprising graphitizing carbon fiber having a strength of 500 kgf/mm.sup.2 or more and a modulus of elasticity of from 27,000 to 33,000 kgf/mm.sup.2, and having at least on the surface of the fibers, from 0.2 to 2% by weight of an epoxy resin as a sizing agent, from 0.005 to 0.10% by weight of silicon and 0.005 to 0.02% by weight of phosphorus based on the weight of carbon fiber having said epoxy resin, silicon and phosphorus.
