A metal-air battery (1) includes a porous negative electrode (3) having a tubular shape and containing a metal, a porous positive electrode (2) having a tubular shape that surrounds the outer surface of the negative electrode (3), and an electrolyte layer (4) disposed between the negative electrode (3) and the positive electrode (2) and containing electrolyte solution. A filled part (31) enclosed by the inner surface of the negative electrode (3) is filled with electrolyte solution, and the electrolyte layer (4) is in communication with the filled part (31) via the porous negative electrode (3). The metal-air battery (1) further includes a supply-collection part (6) for collecting electrolyte solution in the filled part (31) and supplying electrolyte solution to the filled part (31). This facilitates replacement or the like of the electrolyte solution contained in the electrolyte layer (4). |
