Abstract: Disclosed is a method of manufacturing an alkaline secondary battery improved in the positive electrode utilization, the large-current discharge characteristic, the discharge capacity, and the capacity recovery ratio after storage. This method of manufacturing an alkaline secondary battery comprising a positive electrode containing a nickel compound and a cobalt compound, a negative electrode and an alkaline electrolyte, the method comprising the step of performing initial charging which comprises a charging process of supplying a current I (mA) satisfying the following Inequality (1):50<(T.times.C.sup.2)/(I.times.S)<2000 (1)where C is a electrochemical capacity (mAh) of the cobalt compound contained in the positive electrode, which is calculated on the basis of a electrochemical equivalent of the cobalt compound, T is a temperature (.degree.C.) at which the charging process is performed, and S is an area (cm.sup.2) of the positive electrode.
