description PROBLEM TO BE SOLVED: To provide a lead acid battery preventing a dendrite short circuit occurring at an upper side part of a separator.SOLUTION: A lead acid battery includes an electrode plate group in which a positive electrode plate and a negative electrode plate are disposed with a sheet-like separator 1 interposed therebetween. The thickness of the separator at an upper side part is thinner than the thickness of the separator at a lower side part. In particular, ribs 11 are formed from an upper side to a lower side on the surface of the separator 1, and the rib height at an upper side part 1x of the separator 1 is lower than the rib height at a lower side part 1y of the separator 1.SELECTED DRAWING: Figure 2 【課題】セパレータの上側部分で生じるデンドライトショートを防ぐ鉛蓄電池の提供。【解決手段】正極板及び負極板がシート状のセパレータ１を介して配置された極板群を有する鉛蓄電池であって、前記セパレータの上側部分における厚みは、前記セパレータの下側部分における厚みよりも薄い。特にセパレータ１の表面の上下に亘ってリブ１１が形成されており、セパレータ１の上側部分１ｘにおけるリブ高さが、セパレータ１の下側部分１ｙにおけるリブ高さよりも低くなる様に構成されている鉛蓄電池。【選択図】図２
