A manufacturing method of a porous carbon material includes the following steps. A polymer template is provided, the polymer template includes a polymer compound, and the polymer template has a plurality of pores. A coating step is performed, wherein a metal compound is coated on the polymer template to form a transition intermediate. A heating step is performed, wherein the transition intermediate is heated to transform the polymer template to a carbon template and transform the metal compound to a coating layer, and a porous carbon composite material is formed. A removing step is performed, wherein the coating layer is removed from the porous carbon composite material, and a porous carbon material is obtained.
