Abstract: A method for producing metal titanium by carrying out electrolysis using an anode and a cathode in a molten salt bath, the method using an anode containing metal titanium as the anode, the method comprising a titanium deposition step of depositing metal titanium on the cathode, wherein, in the titanium deposition step, a temperature of the molten salt bath is from 250° C. or more and 600° C. or less, and an average current density of the cathode in a period from the start to 30 minutes later of the titanium deposition step is maintained in a range of 0.01 A/cm2 to 0.09 A/cm2.
