摘要： This invention provides an electrolytic apparatus for producing fluorine or nitrogen trifluoride by electrolyzing a molten salt containing hydrogen fluoride, which electrolytic apparatus does not cause any anode effect even at high current density and can be operated without anodic dissolution. The electrolytic apparatus is an apparatus for producing fluorine or nitrogen trifluoride by electrolyzing a hydrogen fluoride-containing molten salt at an applied current density of 1 to 1,000 A/dm 2 and is characterized in that an electrode covered with an electroconductive diamond is used as an anode.
