PROBLEM TO BE SOLVED: To provide a manufacturing method of pole plates for batteries, which can restrain warping at cutting after rolling strip porous plates with an adhesive applied, and has no fear of generating defects of pole plates or short-circuiting defects or defects at the time of insertion into a battery case. SOLUTION: One or a plurality of rows of plain parts 4 are formed between plain parts at both sides and, with the use of a strip porous plate 1 with drilled parts 6 with an innumerable holes 5 arranged in dispersion between these plain parts 3, 4 and 4, 4, the drilled parts 5 of this strip porous plate is applied with an adhesive to make up a coated part 7, by rolling which, difference in extension of both sides and the center part is made small to minimize warping at a cutting process, and afterwards, they are cut in suitable size to form pole plates 10. |
