Abstract
A carbon nano-fiber, particularly twisted carbon nano-fiber such as a carbon nano-coil, carbon nano-twist, carbon nano-rope is produced by means of a catalyst CVD method using carbon-containing gas as a raw material and a catalyst comprising one or plural components selected from the group consisting of Cr, Mn, Fe, Co, Ni and oxide thereof and one or plural components selected from the group consisting of Cu, Al, Si, Ti, V, Nb, Mo, Hf, Ta, W and oxide thereof is used.
