A time for doping an electrode material on an electrode sheet with a lithium ion can be reduced. The electrode manufacturing apparatus includes a processing chamber 200 to and from which the electrode sheet is loaded and unloaded; and a lithium thermal spraying unit 210 configured to dope a carbon material C with the lithium ion by forming a lithium thin film on the carbon material of the electrode sheet W loaded into the processing chamber while melting and spraying lithium-containing powder. Further, the lithium thermal spraying unit 210 includes a lithium-containing powder supply unit 250 configured to discharge the lithium-containing powder toward the electrode material of the electrode sheet, and at least one heating gas supply unit 260 configured to supply a heating gas that melts the lithium-containing powder discharged from the lithium-containing powder supply unit.
