PROBLEM TO BE SOLVED: To provide a manufacturing method which can manufacture an electrode plate for a battery with large active material per unit volume without trouble. SOLUTION: A core material exposed part 24 is formed with active material removed, by giving ultrasound vibration over a marginal part of active material- filled part 22 with active material filled all over a thin-plate core material 21 with porous nature. Lead hoops 9 are bonded by welding to given places along marginal parts in the core material exposed part 24, the part of the core material exposed part 24 where the lead hoops are not yet bonded is compressed toward the active material-filled part 22 to make it in minimal width. The active material-filled part 22 and the lead hoops 9 are cut out in specified dimension to divide into individual electrode plates 28 for a battery. Or, after the lead hoops are bonded, they are cut out in specified dimension to divide into individual electrode base bodies 32, and the part of each electrode base body where the lead hoops 9 are not yet bonded to the core material exposed part 24 is compressed to a minimal width, to make each electrode base body 32 an electrode plate 28. |
