Nickel electrode for alkaline storage battery and method of manufacturing the same

A method of manufacturing a nickel electrode for an alkaline storage battery, comprising:

• a step for filling a conductive porous substrate with a main active material substantially made of nickel hydroxide, the main active material containing cobalt at a metal molar ratio of 0.5% to 3.0% in a state of a solid solution;
• and
• a step for forming a compound layer containing at least one element selected from the group consisting of calcium, aluminum, strontium, scandium, yttrium, and lanthanoide series, on a surface of the main active material.
