To regularize a potential distribution of a grid, prevent local corrosion and prolong product lifetime, a storage battery grid includes frame skeleton (2) in a rectangular shape, a lug portion (21) formed upward from an upper side (2a) of the frame skeleton (2), one or more of main vertical skeletons (3X) extending downward from the lug portion (21) in the frame skeleton (2); and a plurality of diagonal skeletons (4) that branch from at least the main vertical skeletons (3X) extending to both sides with the main vertical skeletons (3X) as axes, and that extend diagonally from the upper side (2a) to the lower side (2b). The plurality of diagonal skeletons (4) are disposed at intervals in a direction of extension of the main vertical skeletons (3X), and at least partial of the plurality of spaces demarcated with the main vertical skeletons (3X) as a portion of the sides are in a substantially quadrilateral shape.
