A grid plate (20) for a lead acid storage battery comprising a frame section (21) having a pair of quadrangular contour shape, and longitudinal grid strands (24) and lateral grid strands (23) that form a grid inside the frame section (21). The longitudinal grid strands (24) and lateral grid strands (23) are composed of thick strands (23b, 24b) of smaller thickness than the frame section (21), and thin strands (23a, 24a) of smaller width and thickness than the thick strands (23b, 24b). The thick strands (23b, 24b) and thin strands (23a, 24a) are arranged so that the strands adjacent to the thick strands (23b, 24b) are thin strands (23a, 24a), and space is reliably provided for facilitating the flow of active material to the sides of the thick strands (23b, 24b). The two ends of the thick strands (23b, 24b) in the thickness direction are positioned further inward from the two end faces of the frame section (21) in the thickness direction, and the end portions of one end side of the thin strands (23a, 24a) in the thickness direction are positioned in positions offset to one end side of the thick strands (23b, 24b) in the thickness direction, whereby the active material is readily packed into the reverse surface side of the grid plate (20). |
