PURPOSE:To provide the titled device which improves the efficiency of recovering gaseous chlorine by the constitution consisting in providing many eaves-like projections inclining forward to a circular cylindrical anode having internally a vertical gaseous chlorine rising hole over the entire width of the working surface thereof thereby capturing the gaseous chlorine. CONSTITUTION:At least one set of an electrode pair each consisting of the circular cylindrical graphitic anode 5 and the cylindrical surface-shaped cathode 8 made of an iron material enclosing the same is disposed into a hermetic vessel 2 to constitute a device for electrolyzing the molten chloride of an alkal metal or alkaline earth metal such as LiCl, NaCl or MgCl2. The eaves-like projections 13 which incline forward and overhang are provided to the anode 5 facing the working surface of the cathode 8 over the entire width of the working surface thereof in the above mentioned device. Capturing grooves are formed of the bottom surfaces thereof and the front of the base parts. Such capturing grooves and the vertical gaseous chlorine rising hole 15 provided in the anode material 5 are connected by connecting holes 14 which are graded upward toward the inside. The gaseous chlorine formed on the working surface of the anode 5 is efficiently recovered by the above-mentioned constitution, by which the constition of the electrolyzing device having high productivity is made possible.
