PROBLEM TO BE SOLVED: To roughly refine fluorine gas in a simple structure without requiring to stop an electrolytic cell in the process of rough refining of fluorine gas. SOLUTION: An apparatus for generating fluorine gas is provided, including: an electrolytic cell 1 segmented into a first gas chamber 11a where fluorine gas generated on an anode 7 is introduced and a second gas chamber 12a where hydrogen gas generated on a cathode 8 is introduced; and a rough-refining device 50 roughly refining hydrogen fluoride gas by condensing hydrogen fluoride gas, which is vaporized from a molten salt in the electrolytic cell 1 and mixed into the main product gas. The rough-refining device 50 includes: a hydrogen fluoride reservoir 51 capable of reserving hydrogen fluoride condensed while the main product gas passes; and a cooling device 52 cooling the hydrogen fluoride reservoir 51 at a temperature higher than the melting point of hydrogen fluoride. The hydrogen fluoride reservoir 51 includes a condensation cell 54 having a vapor phase portion where the main product gas passes and a discharge cell 55 discharging the hydrogen fluoride to the outside by supplying a carrier gas into the hydrogen fluoride liquid, wherein the liquid phase portions of the condensation cell 54 and the discharge cell 55 are connected, while the vapor phase portions 54a, 55a are separated from each other.
