Abstract: A molten salt electrolyzer having a metal collection chamber, an electrolysis chamber, and two or more electrolytic cell units positioned in the electrolysis chamber. Each electrolytic cell unit has a cathode having an inner space in a prism form; at least one bipolar electrode in a rectangular cylinder form and disposed in the cathode inner space; and an anode in a prism form and disposed in an inner space of the bipolar electrode. At least part of individual planes forming an outer side of the bipolar electrode closest to the cathode faces a plane forming the prism-form inner space of the cathode. At least part of individual planes forming the inner side of the bipolar electrode closest to the anode faces a plane forming the prism of the anode. At least one plane of the cathode constitutes one plane of a cathode of another electrolytic cell unit.
