Abstract
An air battery includes a positive electrode using oxygen as a positive electrode active material, a negative electrode containing metal as a negative electrode active material, and a sheet layer interposed between the positive electrode and the negative electrode. The positive electrode is formed in a solid state containing an electrolyte for ionizing the metal of the negative electrode and conductive particles. The sheet layer is made of a material containing no electrolytic solution and exhibiting hygroscopic properties. The sheet layer allows the electrolyte contained in the positive electrode to penetrate toward the negative electrode, and allows metal ions generated in the negative electrode to penetrate toward the positive electrode.
