This lead-acid battery current collector (214) is provided with a frame-shape frame rib part (310) and a lattice part which is formed inside of the frame rib part (310) and has inner ribs. The outer peripheral surface of at least part of the inner ribs in the lattice part includes a first outer peripheral portion (431) where a fibrous material is exposed and a second outer peripheral portion (432) where a particulate material is exposed, and, in a prescribed cross-section approximately perpendicular to the direction of extension of the inner ribs, at least part of the inner ribs are configured such that the length of the first outer peripheral portion is longer than the length of the second outer peripheral portion. 本发明是一种铅蓄电池用集电体(214)，具备框状的框骨部(310)和形成于框骨部(310)的内侧并具有内骨的格栅部。格栅部的至少一部分的内骨的外周面包含纤维状组织露出的第1外周部(431)和粒状组织露出的第2外周部(432)，至少一部分的内骨构成为：在与该内骨的延伸方向大致垂直的规定的截面中，第1外周部的长度比第2外周部的长度长。
