PURPOSE:To manufacture a high-quality carbon fiber having uniform aspect ratio, continuously, in vapor-phase, in high productivity, by mixing carbon monoxide gas, vapor of an organic transition metal compound and a carrier gas, and heating the gaseous mixture. CONSTITUTION:For example, the vapor of an organic transition metal compound [preferably (C2H5)2Fe, etc.], carrier gas such as Ar, and carbon monoxide gas are supplied from the reservoir 1 of the organic transition metal compound, the carrier gas introducing pipe 2 and the carbon monoxide gas introducing pipe 3, and the mixed gas is heated in the reaction tube 9 furnished with the heating furnace 8 to effect the vapor-phase formation of carbon fiber. The heating temperature of the mixed gas is preferably 1,050-1,200 deg.C.
