PROBLEM TO BE SOLVED: To provide a lead-acid battery capable of restraining a welding defect of a connection part between cells caused by intrusion of a resin into a blow hole formed in the connection part between the cells of a mono-block type lead-acid battery with a plurality of the cells integrated, and of exerting an excellent corrosion-resisting effect of Ag in using a Pb-Sn-Ag-based alloy, and having stable life performance. SOLUTION: This lead-acid battery is characterized by using the Pb-Sn-Ag-based alloy for the connection parts between the cells, and by using a denatured polyphenylene ether resin (PPE) or an acrylnitrile-butadiene-styrene resin (ABS) for a battery jar resin material.
