A manganese dry battery includes an anode zinc can made of a zinc alloy containing 0.001 - 0.5 wt% of titanium and at least one element selected from the group consisting of 0.001 - 0.05 wt% of indium and 0.001 - 0.05 wt% of bismuth, or a zinc alloy further containing 0.01 - 0.4 wt% of lead. Even without heavy metals such as Hg and Cd, the zinc alloy anode can has a corrosion-resistant property and mechanical strength equivalent to or greater than those of the conventional zinc anode can, thereby giving a low pollution zinc-carbon battery having a storage characteristic equivalent or superior to that of the conventional zinc anode can.
