PURPOSE:To increase the hydrogen overvoltage of an electrode of a primary cell and to prevent the corrosion by adding prescribed percentages of Ga, In and Pb to Zn. CONSTITUTION:This Zn alloy for an electrode contains 0.01-0.5% Ga and 0.01- 0.5% Pb or further contains 0.001-0.01% In. Though the amounts of expensive Ga and In added are small, by adding a little Pb, the hydrogen overvoltage of an electrode of a primary cell made of the Zn alloy is increased, and the corrosion is prevented.
