Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a lead acid storage battery in which deterioration of a positive electrode plate due to corrosion of a positive electrode lattice is suppressed and which has a long life in the lead acid storage battery provided with the positive electrode lattice of Pb-Ca-Sn alloy. SOLUTION: In the lead acid storage battery provided with the positive electrode lattice consisting of the Pb-Ca-Sn alloy, this Pb-Ca-Sn alloy contains Ba of 0.001 wt% to 0.05 wt% and Se of 0.001 wt% to 0.05 wt%. Then, it is more preferable that as the positive electrode lattice, an expand lattice obtained by expand-working the rolled body of this Pb-Ca-Sn alloy is used. COPYRIGHT: (C)2006,JPO&NCIPI
