Abstract: An object of the present invention is to inhibit intergranular corrosion of a lead alloy by grain refining, and to prolong the life and improve the reliability of a lead battery using the alloy for a positive current collector in the battery. The intergranular corrosion of the lead alloy is inhibited by adding Sr to a Pb—Sn alloy to refine a cast structure and the recrystallized structure of a rolled material, and the hardness is improved by further adding Ca, Ba and Te. In addition, the rolled sheet of the lead alloy is used in the positive current collector of the lead storage battery.
