    • Provided is a process for producing a single-walled carbon nanotube on a substrate on which a lot of fine particles comprising at least one kind of a catalyst metal are formed in a reaction apparatus maintained in vacuum, wherein at least one kind of fullerene C2n's (n is an integer of n≧18) is sublimated at a prescribed temperature or higher to produce a fullerene gas in which a partial pressure is controlled; the fullerene gas is transported on the substrate heated at a sublimation temperature of the fullerene or higher; and the fullerene gas is brought into contact with the catalyst metal fine particles described above to produce a single-walled carbon nanotube. The vacuum degree is preferably 0.5 Torr or less, and the sublimation temperature is preferably 700° C. or higher. The substrate has a thin film of a porous substance or an inorganic oxide, and transition metal catalyst fine particles having a particle diameter of 0.5 to 10 nm are formed on the above thin film.
