PROBLEM TO BE SOLVED: To improve discharging after long-term storage, that is, a shelf life greatly by forming a conductive film on a positive electrode can inside face in an alkaline battery comprising a positive electrode molding mix inserted into the positive electrode can serving as a terminal and brought into electrical contact with the inside face of the positive electrode can in its inserted state. SOLUTION: The conductive film 4 is formed on the inside face 21 of the positive electrode can 2 in contact with the positive electrode molding mix 3, while the surface roughness of the conductive coating 4 is set >=10μm (Ry value).
