The present invention provides an alkaline battery capable of improving the deterioration of capacity retention due to the generation of hydrogen gas, the deterioration of leakage resistance due to the increase of internal pressure, and the swelling of the battery. A disk-shaped positive electrode mixture 1 is accommodated and disposed inside a positive electrode can 2. Positive electrode mixture 1, a composite oxide of A g x Co y Ni z O 2 silver, cobalt, and nickel expressed by (x + y + z = 2 , x ≦ 1.10, y> 0.), Oxide It contains at least one of silver (Ag 2 O) and manganese dioxide (MnO 2 ).
