PROBLEM TO BE SOLVED: To provide a method for manufacturing metal lithium by which a simple substance of metal lithium as an active metal can easily be manufactured in high purity without generating gaseous chlorine. SOLUTION: In the method for manufacturing metal lithium, an electrolytic apparatus is prepared which has an electrolytic chamber divided by a diaphragm for baths into cathodic and anodic electrolytic chambers and the anode and cathode disposed in the respective electrolytic chambers. At least part of the diaphragm for baths is formed with a porous material capable of conducting electricity and transferring lithium ions. An anodic electrolytic bath consisting of 0.1-30 mass% lithium carbonate and a fluoride and a cathodic electrolytic bath made of only a fluoride are fed into the respective electrolytic chambers of the electrolytic apparatus and electrolytic reduction is carried out under the electrolytic conditions of 2-500 A/cm<2> cathode current density and 600-1,000 deg.C electrolytic temperature.
