PROBLEM TO BE SOLVED: To provide a flat battery capable of suppressing reduction in productivity, and of enabling cost reduction. SOLUTION: The flat battery 10 includes: a positive electrode can 1; a positive electrode mixture 2; a separator 3; an electrolytic solution retaining layer 4; a gasket 5; a negative electrode binder 6; and a negative electrode can 7. The positive electrode mixture 2 is composed of granular silver oxide, silver nickel complex oxide, and graphite. A particle diameter of the granular silver oxide is 50μm to 500μm, and the particle diameter of the silver nickel complex oxide is approximately 10μm. A weight ratio of the granular silver oxide is within a range of 85 to 98.8 wt.% against all the positive electrode mixture 2. The weight ratio of graphite is within the range of 0.2 to 5 wt.% against all the positive electrode mixture 2. The weight ratio of the silver nickel complex oxide is within the range of 1 to 10 wt.%, preferably within the range of 1 to 5 wt.% against all the positive electrode mixture 2.
