A nickel hydroxide positive active material for an alkaline battery contains nickel hydroxide powder having a nickel valence of greater than 2; and a cobalt compound having a cobalt valence of greater than 2, which is formed on the surface of said nickel hydroxide powder. For example, the surface of nickel oxyhydroxide powder is covered by cobalt oxyhydroxide layer. This positive active material is used as a starting material to produce an electrode by retaining it in a three-dimensional porous material.
