PROBLEM TO BE SOLVED: To provide a molten salt electrolysis tank capable of improving a lifetime of an electrode and efficiency of electrolysis by preventing residence of molten salt and growth of a deposit of an electrolytic deposition metal on an electrode corner part.SOLUTION: In a molten salt electrolysis tank formed by arraying two or more electrodes, the electrode has a shape in which a distance in the array direction from an adjacent electrode becomes longer at an electrode tip part, by a method in which (a) the tip part forms a semicircular curve, or (b) the width thereof becomes smaller gradually toward the tip part, or (c) a chamfering part is formed regarding a cross-sectional shape in the thickness direction.SELECTED DRAWING: Figure 3 |
