Disclosed is an air battery (A1) having a cathode layer (1), an anode layer (2) and an electrolyte layer (3) interposed between the cathode and anode layers (1, 2). At least one of the cathode and anode layers (1, 2) has a passage forming member (5) such that, when the air battery (A1) is adjacently stacked to another air battery (A1), the passage forming member (5) is situated between the air battery (A1) and the adjacent air battery (A1) so as to form an air passage (F) to cathode layer (1). The passage forming member (5) has conductivity and the ability to be elastically deformed according to expansion of the electrolyte layer (3). It is possible by this structure to, when there occurs increase in internal resistance due to expansion of the electrolyte layer, compensate such increase in internal resistance by decrease in contact resistance, maintain the cross-sectional area of the air passage at a predetermined size and prevent decrease in the output of the air battery. |
