Zusammenfassung:	To suppress the occurrence of peeling at the interface of a metal-air battery.SOLUTION: A metal-air battery 1 includes an air electrode 2 including a water-repellent film 21 in an exterior body having an opening 42, and a metal pole. A packaging material constituting the exterior body has a welded region 43 in which the water-repellent film 21 is welded to the peripheral edge of the opening 42. The welded region 43 includes a first convex portion 431 and a second convex portion 432 that bulge outward at least on the outer circumferential side and the inner circumferential side of the welding region 43. The air electrode 2 is arranged so as to overlap the first convex portion 431 on the outer peripheral side with the water-repellent film 21 in between.SELECTED DRAWING: Figure 9B 【課題】金属空気電池の界面における剥離の発生を抑制する。【解決手段】金属空気電池１は、開口部４２を有する外装体内に、撥水膜２１を含む空気極２と、金属極とを備える。外装体を構成する包材は、開口部４２の周縁部に、撥水膜２１が溶着されてなる溶着領域４３を有する。溶着領域４３は、少なくともその溶着領域４３の外周側と内周側とに、外方へ膨出する第１凸状部４３１と第２凸状部４３２とを備える。空気極２は、撥水膜２１を介して、外周側の第１凸状部４３１と重なりを有するように配置されてなる。【選択図】図９Ｂ
