PROBLEM TO BE SOLVED: To provide a zinc-alkaline battery having excellent high-load discharge characteristic and leak resistance at the time of overdischarge. SOLUTION: The zinc-alkaline battery includes a negative electrode, a positive electrode, a separator, and an electrolyte. The negative electrode contains a zinc alloy powder including 20 to 50 wt.% of a micropowder with a particle size of 75μm or less. In a constant resistance discharge, a time period for the negative electrode potential to rise is shorter than a time period for the positive electrode potential to fall. COPYRIGHT: (C)2008,JPO&INPIT
