METHOD AND APPARATUS FOR MANUFACTURING FIBER ESSENTIALLY CONSISTING OF CARBON AND ELECTRON RELEASING ELEMENT USING THIS FIBER

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus capable of manufacturing a fiber essentially consisting of carbon functioning as an electron releasing member of excellent performance which are simple in processes and are low in a manufacturing cost and the electron releasing member having this fiber. SOLUTION: The method of manufacturing fiber essentially consisting of the carbon includes a process step of heating a substrate having a catalyst material within a vessel in which carbon-containing gas exists and is below 5 vol.% in oxygen concentration based on the volume of the vessel.
