Abstract
Provided is a cylindrical alkaline battery in which the packing density Dc of the manganese dioxide in the positive electrode is 2.8 to 3.0 g/cmand the packing density Da of zinc or a zinc alloy in the negative electrode is 2.0 to 2.3 g/cm. The packing density Dc of the manganese dioxide, the packing density Da of the zinc or zinc alloy, the thickness Tc of the positive electrode in a radial direction, and the thickness Ta of the negative electrode in a radial direction satisfy one of the following relational formulas (1) to (3):−1.975×()+2.745<<−1.690×()+2.734  (1)−11.652×()+14.470×()−3.095<<11.652×()−18.420×()+8.585  (2)−8.895×()+12.864×()−3.258<<8.895×()−16.244×()+8.726  (3).
