Disclosed are a porous graphene member having through-holes formed therein, a method for manufacturing the porous graphene member, and an apparatus for manufacturing the porous graphene member using the method. The method comprises: introducing a carbon source and a substitution reaction source into a deposition furnace; thermally decomposing the carbon source and the substitution reaction source simultaneously to generate carbon atoms and substitution atoms, respectively, wherein the carbon atoms are deposited on a substrate present within the deposition furnace to form a graphene film consisting of a monoatomic layer structure, and during the deposition of carbon atoms, the substitution atoms not only interfere with covalent bonds between the carbon atoms to cause crystal defects, but also substitute for parts of the carbon atoms to in situ form through-holes in the graphene, thereby creating the porous graphene member; and releasing the porous graphene member from the substrate.
