PROBLEM TO BE SOLVED: To provide a lead-acid battery having excellent service life performance. SOLUTION: This lattice for lead-acid batteries is characterized by having a first layer 51 made of a lead alloy, a second layer 52 made of a lead alloy and disposed on one side of the first layer, and a third layer 53 made of lead or a lead alloy and disposed between the first and second layers, the third layer being softer than the first and second layers. For example, a lead-calcium alloy can be mentioned as the first layer, a calcium-rich lead-calcium alloy as the second layer, and pure lead or a lead-tin alloy as the third layer.
