CYLINDRICAL ALKALINE BATTERY

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/cm 3 and the packing density Da of zinc or a zinc alloy in the negative electrode is 2.0 to 2.3 g/cm 3 . 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 × Tc / Ta + 2.745 < Dc / Da < - 1.690 × Tc / Ta + 2.734 - 11.652 × Tc / Ta 2 + 14.470 × Tc / Ta - 3.095 < Dc / Da < 11.652 × Tc / Ta 2 - 18.420 × Tc / Ta + 8.585 - 8.895 × Tc / Ta 2 + 12.864 × Tc / Ta - 3.258 < Dc / Da < 8.895 × Tc / Ta 2 - 16.244 × Tc / Ta + 8.726
