Abstract: A highly efficient and effective activating method by which the electrochemical activity of a hydrogen storage alloy is improved and a hydrogen storage alloy electrode having an excellent initial internal pressure characteristic, low-temperature discharge characteristic, high-rate discharge characteristic, and cycle characteristic and manufactured by using the activating method. A process for producing a hydrogen storage alloy electrode includes an alloy activating step in which a hydrogen storage alloy is dipped in strong acidic solution containing metallic ions and the pH value rise of the solution is accelerated by adding an alkali to the solution.
