A manufacturing method of a porous carbon nano fiber by using camphor and a carbon nano fiber manufactured by the same are provided to perform a carbonization process after the oxidation stabilization, thereby manufacturing the porous carbon nano fiber. The carbon nano fiber precursor, camphor and a solvent are mixed with each other and then the mixed solution is provided. The electric-spinning of the solution is performed so that the nano fiber is obtained. The oxidation stabilization of nano fiber is performed and thereafter the nano fiber is carbonated. The camphor is volatilized by the oxidation process and carbonation process. The camphor contents is 100-200 wt % of the carbon nano fiber precursor.
