Abstract
A metal-air battery (1) includes a tubular positive electrode (2), a negative electrode (3) opposing an inner side surface of the positive electrode (2), and an electrolyte layer (4) disposed between the negative electrode (3) and the positive electrode (2). The positive electrode (2) includes a porous positive electrode main body (21) that is made of conductive ceramic and serves as a tubular supporter, and a separator (41) that is a porous film made of ceramic having insulating properties is formed on the inner side surface of the positive electrode main body (21). Using the positive electrode main body (21) as a supporter makes it possible to easily increase the thickness of the positive electrode (2) and to thereby reduce the electrical resistance of the positive electrode (2) and improve the battery performance of the metal-air battery (1).
