Provided is a nickel electrode for an alkaline battery having a desired thickness and capacity, and capable of suppressing deterioration of battery performance due to charge / discharge, and a method for producing the same. After filling the electrode substrate with the active material, it is pressure-molded and further subjected to heat treatment at 80 ° C. or higher and 130 ° C. or lower for 5 minutes or longer and 60 minutes or shorter to obtain an electrode. The pressure molding is performed using an electrode substrate having a thickness of 2.3 t or less, where t is the thickness of the electrode after pressure molding. By defining the ratio of compressing the electrode substrate after being filled with the active material, the thickness of the electrode substrate can be set to a thickness capable of filling a sufficient amount of the active material, and the filled active material is the electrode substrate. It can be difficult to peel off. Further, the nickel electrode can be solidified in a compressed state by performing a predetermined heat treatment after the pressure forming.
