Abstract
In a metal-air battery (), an interconnector () formed of ceramic having alkali resistance is provided on the surface of a porous positive electrode layer () on the side opposite to the surface that is in contact with an electrolyte layer (). A liquid repellent layer () having liquid repellency to an electrolyte solution is further provided on the surface of the positive electrode layer () on which the interconnector () is formed, and covers this surface along with the interconnector (). The metal-air battery () using an alkaline electrolyte solution can thus easily prevent leakage of the electrolyte solution by the interconnector () and the liquid repellent layer () while suppressing degradation of the interconnector ().
