An object of the present invention is to provide a method and apparatus capable of continuously producing organic nanotubes, wherein an organic nanotube material dispersion solution consisting of an organic nanotube material and an organic solvent is pressurized and caused to pass through a very narrow orifice. An apparatus for producing organic nanotubes according to the present invention includes: a tank that contains an organic nanotube material dispersion solution consisting of an organic nanotube material and an organic solvent； a pump that pressurizes the organic nanotube material dispersion solution from the tank so that the organic nanotube material dispersion solution is carried under high pressure； a cylindrical casing for continuously flowing the organic nanotube material dispersion solution carried from the pump under pressure； an orifice being placed in the cylindrical casing； an organic nanotube precipitation pipe being coupled to an outlet of the cylindrical casing； and drying means following the organic nanotube precipitation pipe.
