To provide a manufacturing method for a plate, capable of reducing the weight of the plate and improving productivity without deteriorating battery performance when an expanded lattice is applied to a large-sized lead-acid battery.

This manufacturing method for a plate for a lead-acid battery has a process for continuously expanding and developing a lead or a lead alloy sheet, a process for punching a specified part, a process for cutting the sheet into the specified size, and a process for filling active material paste. After the sheet is cut into the specified size, it is rotated by 90°, and the active material paste is filled except collecting lug parts.
