Abstract

A grid plate for a lead acid storage battery including a frame section having a pair of quadrangular contour shape, and longitudinal and lateral grid strands forming a frame section grid. The longitudinal and lateral grid strands have thick strands of smaller thickness than the frame section, and thin strands of smaller width and thickness than the thick strands. Strands adjacent to the thick strands are thin strands, and space allows flow of active material to sides of the thick strands. Ends of the thick strands in the thickness direction are positioned further inward from end faces of the frame section in the thickness direction, and the end portions of one end side of the thin strands in the thickness direction are positioned offset to one end side of the thick strands in the thickness direction, and active material is packed into the reverse surface side of the grid plate.
