The present invention relates to a method for manufacturing a hollow heat source. A method for manufacturing a hollow heat source provides a carbon nanotube structure, the carbon nanotube structure having a plurality of micropores, a hollow support, and the carbon nanotube structure being the hollow Providing on the surface of the substrate, providing a first electrode and a second electrode spaced apart to electrically connect with the carbon nanotube structure, and providing a preform of the substrate, Forming a heating element by combining the preform of the substrate and the carbon nanotube structure.
