PROBLEM TO BE SOLVED: To provide a method for manufacturing sponge titanium by which of molten magnesium chloride by-produced in magnesium reduction of titanium tetrachloride is discharged so as to be precisely controlled to the objective weight for a short time, and to provide a discharge controlling device. SOLUTION: In the method for producing sponge titanium in which titanium tetrachloride and metallic magnesium are brought into reduction reaction in a vessel to produce sponge titanium, at the time of feeding an inert gas into a vessel 1, pressurizing the inside of the vessel 1 and discharging magnesium chloride by-produced in the process of the reduction reaction from the vessel 1, the discharge weight and/or discharge speed of magnesium chloride is detected, and the amount of the inert gas to be fed in controlled, by which the discharge rate is controlled to the range of 2 to 10 Kg/sec.
