The invention of present application relates to a method for enabling a hybrid carbon nanotube having an arbitrary composition ratio to be readily manufactured, and the hybrid carbon nanotube. A method for manufacturing a hybrid carbon nanotube, which comprises immersing a carbon nanotube having open pores in a solution having a dopant substance dissolved therein to effect a doping reaction, thereby preparing a hybrid carbon nanotube comprising a carbon nanotube and a dopant substance introduced therein.
