摘要： An object of the present invention is to provide a metal-air battery capable of achieving high enough output (maximum power) to be applicable to use such as charging a cell phone. The metal-air battery of the present invention uses a metal as an active material of a negative electrode 30 and oxygen in the air as an active material of a positive electrode 20. The positive electrode 20 comprises a current collector 21 composed of a plate-like porous metal material and a conductive material layer 23 disposed on one surface side of the current collector 21. At least one surface of the current collector 21 on which the conductive material layer 23 is disposed is coated with a conductive coating material to form a coating conductive film 25.
