PROBLEM TO BE SOLVED: To provide a high-quality alkaline battery which can prevent falling-off of active materials by increasing adhesive strength onto a core body of an active material layer on an opposite side, where an active material layer is scraped off. SOLUTION: Hydrogen storage alloy slurry obtained by adding hydrogen storage alloy powder 12a to polyethylene oxide(PEO) powder as a binder 12b and a suitable amount of water (solvent for the binder) and kneading them is applied on both sides of a metal core body (active material holder) 11 made of punching metal, and then dried. Furthermore, after an active material layer 13 is removed from the core body 11 with a means such as cutting, a prescribe amount of water (solvent for the binder) is sprayed on the cut face (expose face of the core body 11) to adhere water, and then is dried, to obtain a hydrogen storage alloy electrode 10 arranged on the outermost side of an electrode group. |
