PROBLEM TO BE SOLVED: To provide an alkaline battery which prevents trouble such as generation of dust and corrosion of a positive electrode can at the end of an opening sealing side of the positive electrode can and has high quality hold performance.SOLUTION: Disclosed is an alkaline battery 1 which includes a positive electrode mixture annularly formed in a bottomed cylindrical positive electrode can 2 serving as a positive electrode, a negative electrode gel containing a zinc alloy arranged inside of the positive electrode mixture via a separator, and a negative electrode collector 6 inserted into the negative electrode gel and which is formed by sticking a sheet-like label 20 to the outer peripheral part of the positive electrode can 2. In a portion adjacent to the end of an opening sealing side of at least the positive electrode can 2 out of the surface of the label 20, water repellency of the label 20 surface is set larger than in a residual portion. |
