A method of producing carbon fibers in which an exhaust gas generated in a heat-treating stage of the production of carbon fibers is divided into two portions, one portion thereof being decomposed by the action of an oxidizing catalyst and subsequently being blended with the other portion, to be reused. According to said method, the heat loss in the exhaust gas disposal process can be substantially reduced and the efficiency of heat-treating can be improved and in consequence, various troubles due to the decomposed products contained in the heat-treating atmosphere such as surface damage, fuzziness and individual fiber breakage, etc. can be avoided.
