PROBLEM TO BE SOLVED: To provide a grid for a storage battery, having a plurality of inner bones in a frame bone that improves charging/discharging cycle life time performance by suppressing falling accompanying softening of an active material and such.SOLUTION: The grid for a storage battery includes: a frame bone; and a plurality of inner bones 3 connected to the frame bone. The grid for a storage battery has one or a plurality of salient parts 31 formed by at least part of the inner bones 3 being folded in a grid thickness direction. The salient parts 31 have curved shapes. The grid for a storage battery has a first salient part 31a that is the salient part 31 of the inner bone 3 made to be convex on one side in the grid thickness direction and has a second salient part 31b that is the salient part 31 of the inner bone 3 made to be convex on the other side in the grid thickness direction, while the first salient part 31a and the second salient part 31b are alternately formed. |
