PROBLEM TO BE SOLVED: To provide an alkaline dry cell in which fall-off of a sealing body is prevented when a short circuit or a trouble in charge or the like occurs and which is superior in high-rate characteristics. SOLUTION: The alkaline dry cell is equipped with a bottomed and cylindrical positive electrode can 1 with a thickness of its trunk part 6 of 0.185 mm or more and 0.215 mm or less and with a thickness of its opening part 5 of 1.1 times or more and 1.85 times or less of the thickness of the trunk part 6, a bag-shaped separator 11 arranged in the positive electrode can 1, a gelatinous negative electrode 15 filled into the separator 11, a positive electrode mixture 10 which is arranged between the inner peripheral face of the positive electrode can 1 and the separator 11 and which contains nickel oxyhydroxide, and the sealing body arranged at the opening part 5 of the positive electrode can 1.
