PURPOSE:To obtain a cylindrical alkaline battery excellent in leak fluid resistance by preventing a leak fluid based on an alkaline electrolyte crawling up on the surface of a negative pole collector by an alkaline creep under a high temperature and high humidity. CONSTITUTION:In the peripheral part of a part welded with a head part 5a of a negative pole collector 5 in an internal surface side of a negative pole terminal plate 8, a neutralizer layer 9 consisting of a mixture between boric acid powder of 300mum or less mean grain size and polybutene of 2,500 or more mean molecular weight or of 150,000c.s.t or more kinetic viscosity is provided. |
