ABSTRACT:
An electrode for an electron gun and an electron gun using same are provided which make use of stable carbon material having small work function and which permit orientation control to be achieved and which can be manufactured at a low cost. An electrode for an electron gun uses carbon electrode(s) formed from amorphous carbon and carbon nanotubes or carbon nanofibers and molded in linear shape. The carbon electrode is obtained by mixing a resin composition such as chlorinated vinyl chloride resin, furan resin, etc., which forms non-graphitizing carbon after carbonizing, with a carbon powder such as carbon nanotubes or carbon nanofibers and, after extrusion, molding and carbonizing the molding obtained.
