[PROBLEMS] To provide a high carbon fiber generation efficiency (weight increase) per mass of catalyst, a small temperature dependence of the generation efficiency, a small variation in impurity concentration, excellent packing dispersibility in resins, etc., and electrical conductivity of resins, etc. Provided is a method for efficiently producing carbon fibers that can increase the property and heat conductivity. [I] a compound containing a Co element, [II] a compound containing at least one element selected from the group consisting of Ti, V, Cr and Mn, and [III] a group consisting of W and Mo A step of obtaining a catalyst by dissolving or dispersing a compound containing at least one element selected from the above in a solvent and impregnating the solution or dispersion into a particulate carrier; and a carbon source in the gas phase in the catalyst. The manufacturing method of carbon fiber including the process made to contact. [Selection figure] None |
