PURPOSE:To prevent electrolyte leakage from an air electrode side by improving fixing structure of the circumference of the air electrode to a positive case. CONSTITUTION:An air electrode 11 is placed on a water repellent film 7 which is arranged in the inner bottom of a positive case 4, thereafter a ring-shaped hot melt type adhesive 13 which is molded so as to accommodated on the exposed circumference 12 of a current collecting net 10 of the air electrode 11 is arranged. A ring-shaped metallic member 14 such as nickel ring having excellent corrosion resistance is inserted on the hot melt type adhesive 13, then the nickel ring 14 is pressed with a heated moled 15 so as to melt the hot melt type adhesive and bond together a catalyst member 9, the circumference 12 of the current collecting net 10, and the inner circumference wall of the positive case 4. Thereby, the gap between them is completely filled with the adhesive, and the leakage path of an electrolyte is shut off. |
