A flat-type alkaline primary battery has a positive electrode mixture containing a positive electrode active material, a negative electrode mixture containing a negative electrode active material, and a separator for separating the positive electrode mixture and the negative electrode mixture. An alkaline electrolyte solution is contained in the positive electrode mixture, the negative electrode mixture, and the separator. The negative electrode active material includes zinc or zinc alloy powder. The positive electrode active material includes nickel oxyhydroxide containing cobalt in solid solution, the surface of which is coated with a conductive material.
