The present invention provides an alkaline storage battery comprising a positive electrode containing a nickel hydroxide active material and a compound oxide in a range of 2 wt % to 30 wt % to the amount of the nickel hydroxide. The compound oxide contains at least one transition metal element and at least one rare earth element or alkaline earth metal element. The compound oxide has conductivity of 10.sup.-2 S/cm or higher at 25.degree. C. and stability in an alkaline electrolyte. Consequently, the alkaline storage battery shows excellent characteristics in a long-term preservation at a high temperature, capacity restoration, and charge/discharge cycle life.
