An enclosed alkali storage battery using as a positive active material nickel oxyhydroxide in which Mn of gamma ratio of 65-100 % forms a solid solution, an enclosed alkali storage battery using as a positive active material nickel oxyhydroxide to which a rare earth element and/or a rare earth element compound is added or applied in such a way that the content of the rare earth element is 0.05 - 5 wt.% when a rare earth element compound is added or applied, or an enclosed alkali storage battery using as a positive active material nickel oxyhydroxide such that the half-width of a peak of a lattice plane (003) in an X-ray diffraction pattern is not less than 0.8 DEG in an expression of 2 theta ( theta : Bragg angle). Since the internal pressure of the battery does not increase greatly even after a long-term use over charge/discharge cycles, the electrolyte rarely leaks.
