Abstract
A method for manufacturing carbon nanotubes includes the steps of: preparing metal-containing-nanofibers which include nanofibers made of organic polymer and metal which possesses a catalytic function in forming carbon nanotubes; and forming carbon nanotubes which contain metal therein by using the nanofibers as a carbon source, wherein the carbon nanotubes are formed by putting the metal-containing-nanofibers into a heating vessel which has a substance capable of converting electromagnetic energy into heat, and by heating the metal-containing-nanofibers using heat which is generated by the heating vessel when electromagnetic energy is applied to the heating vessel.
