The utility model provides an alkaline button cell, including positive pole shell, negative pole cover, seal ring, positive pole material, negative pole material and diaphragm, the bottom end of seal ring axially extends downward to the inner bottom surface of positive pole shell and abuts against the inner bottom surface of positive pole shell, the diaphragm is cylindrical, only the bottom end is open, and the bottom end of the diaphragm is open. The bottom edge of the diaphragm extends to the inner bottom surface of the positive electrode shell and abuts against the inner bottom surface of the positive electrode shell, and the inner surface of the diaphragm and the inner bottom surface of the positive electrode shell are enclosed together to form a positive electrode material accommodating cavity, so that when the upper edge of the positive electrode shell is bent inwards, the upper edge of the positive electrode shell is bent inwards; and the sealing ring cannot press the diaphragm and the positive electro
