The invention provides a postive electrode plate for a lead-acid battery, which can improve the service life performance and the initial capacity of the lead-acid battery. A positive electrode plate for a lead-acid battery includes: a punched grid (10) having grid crosspieces; and a positive electrode material (20). A corner portion (15C) of the grid crosspiece of the punched grid (10) in a cross section perpendicular to an extending direction of the grid crosspiece is deformed, and a density of the positive electrode material (20) after being subjected to formation is 4.1 [g/cm3] or more. 本发明提供种铅蓄电池用正极板，可提高铅蓄电池的寿命性能和初始容量。种铅蓄电池所使用的正极板，包括具有格栅框架的冲裁格栅(10)和正极电极材料(20)，上述冲裁格栅(10)的上述格栅框架的与延伸方向垂直的截面的角部(15C)发生有变形，上述正极电极材料(20)的已化成时的密度为4.1[g/cm]以上。
