Abstract
A method of producing vapor growth carbon fibers which are grown in a rection space by thermally decomposing gaseous hydrocarbon and by using transition metal fine particles as the catalyst, wherein the reaction space is filled with ceramic granules which serve as a radiation heat transfer medium and are moved to prevent an intermingling of the growing carbon fibers, so that the grown carbon fibers are conveyed from the reaction space by a gas stream.
