PURPOSE:To solve a problem that an electrolytic solution easily leaks out through air holes of a positive electrode case during storage of an air battery under high temperature and highly humid condition and provide an air battery having high resistance to leakage of an electrolytic solution through air holes. CONSTITUTION:A material composed of a surface layer of a water absorptive fiber 12 and an inner layer of a water unabsorptive fiber 11 is used for a material of air dispersing paper 9, Consequently, an electrolytic solution is prevented from leaking out through air holes even at the time of charging and over discharging in high temperature and highly humid atmosphere. |
