In an alkaline storage battery positive electrode, the surface of positive electrode active material particles is uniformly coated with a conductive agent and the alkaline storage battery positive electrode is capable of suppressing an increase in internal battery resistance. The method of fabricating includes: (A) fixing active material particles to a current collector, the active material particles containing, as a main component, nickel hydroxide coated with a conductive agent, the conductive agent containing, as a main component, at least one kind of cobalt compound selected from the group consisting of cobalt hydroxide, tricobalt tetroxide, and cobalt oxyhydroxide; and (B) reducing the cobalt atom in the cobalt compound such that the cobalt atom has an oxidation number of less than +2, by applying a reduction current in an electrolyte solution to the current collector to which the active material particles are fixed, after the step (A).
