Abstract: In a metal-air battery, a negative electrode, an electrolyte layer, and a positive electrode are concentrically disposed in the stated order, radially outward from the central axis, and the outer circumferential surface of the positive electrode is enclosed by a liquid-repellent layer (29). The liquid-repellent layer (29) includes a relatively high-strength inorganic porous material (292) having a continuous pore structure, and a fluorine-based porous part (293) formed by fusing fluorine-based particles to each other. The fluorine-based porous part (293) is fused to the inorganic porous material (292) in pores (294) of and on the outer surface (295) of the inorganic porous material (292). This makes it possible to provide the liquid-repellent layer (29) that is a functional porous material having desired mechanical strength, gas permeability, and liquid impermeability.
