PURPOSE:To provide a button-shaped air-depolarized cell having stable discharge performance in a wide load range at low cost by improvement to water-repellant film. CONSTITUTION:A porous polyolefine film in which pores are compressed and compacted partly, or in which ink of UV-setting type resin ink is printed partly to reduce porosity is used as a water-repellent film, and this is disposed between an air electrode and a positive electrode case. A film having a high Gurley number and a smaller irregularity of air permeability than a conventional Teflon film can thus be provided, thereby an air-depolarized cell having stable discharge performance in a wide load range can be provided at low cost. |
