Zusammenfassung:	PROBLEM TO BE SOLVED: To avoid fluid leak of an alkaline dry battery which may occur when the alkaline dry battery is arranged in series and dropped.SOLUTION: Disclosed is an alkaline dry battery where an open end 11 of a battery case 1 is sealed with a negative electrode terminal plate 7 with a resin sealing body 5. A shoulder part 12b of a sealing end 12 of the battery case 1 and a central flat plate part 7a of the negative electrode terminal plate 7 are formed of the same material, and the thickness of the shoulder part 12b of the battery case 1 is 0.2-0.4 mm inclusive. When the thickness of the shoulder part 12b of the battery case 1 is represented by Tp [mm] and the thickness of the central flat plate part 7a of the negative electrode terminal plate 7 is represented by Tn [mm], the relation 1.0≤(Tn/Tp)≤2.0 is satisfied.
