Abstract:
1. A method of manufacturing a carbon nanostructure using a furnace tube for growing crystalline carbon by means of vapor deposition from a crystal growth surface of a catalytic base including a catalytic material, said furnace tube being divided by said catalytic base into a feedstock gas supplying side and a carbon nanostructure growth side, the method comprising steps of: supplying at least one carrier gas from said carbon nanostructure growth side to make said carrier gas brought into contact with said crystal growth surface; and supplying at least one feedstock gas from said feedstock gas supplying side to make said feedstock gas brought into contact with the catalytic material on an upstream side of the catalytic base, wherein said at least one feedstock gas is not brought into contact with said crystal growth surface, wherein said at least one feedstock gas and said at least one carrier gas is supplied so that carbon is continuously supplied to said crystalline carbon through inside of said catalytic material.
