Conventional air batteries had room for improvement in relation to increasing conductivity in the in-plane direction (direction along the plane) in a positive electrode. Provided is an air battery (A), comprising a positive electrode (2) and a negative electrode (3) having an electrolyte layer (1) therebetween; wherein the positive electrode (2) comprises a base material layer (21) comprising a conductive porous material, and a conductive coating (23) having higher conductivity than the base material layer (21) and capable of being ventilated is provided on at least one main surface of the base material layer (21). As a result, the conductivity in the in-plane direction in the positive electrode (21) is increased and the resistance overvoltage is reduced. |
