Abstract
An alkaline primary battery includes: a positive electrodecontaining manganese dioxide; an alkaline electrolyte containing zinc oxide; a gelled negative electrodecontaining zinc alloy particles, the alkaline electrolyte, and a gelling agent; and a negative electrode current collectorinserted in the gelled negative electrode. The gelled negative electrodehas a predetermined malleability such that when 4.0 g of the gelled negative electrodeformed into a cylindrical shape with a diameter of 15 mm is extended with 200 g of a load through 10 g of a flat plate, and then an upper surface of the extended gelled negative electrodeis approximated to a circle, this circle has a diameter ranging from 24 mm to 36 mm, both inclusive.
