Summary:PROBLEM TO BE SOLVED: To suppress a short circuit between electrode plates in a lead acid battery.SOLUTION: A lead acid battery 10 includes: a positive electrode plate 30P including a lattice 32 having a frame bone 33; a negative electrode plate 30N; and a separator 40 disposed between the positive electrode plate 30P and the negative electrode plate 30N. The separator 40 includes: a base part 41; and a protrusion 45 protruding from at least one face of the base part 41 and overlapping a corner C of the positive electrode plate 30P as viewed from a thickness direction of the positive electrode plate 30P.SELECTED DRAWING: Figure 11 【課題】極板の短絡を抑制する。【解決手段】鉛蓄電池１０であって、枠骨３３を有する格子３２を備えた正極板３０Ｐと、負極板３０Ｎと、前記正極板３０Ｐと前記負極板３０Ｎとの間に配置されたセパレータ４０と、を含み、前記セパレータ４０は、ベース部４１と、前記ベース部４１の少なくとも一方の面から突出し、前記正極板３０Ｐの厚さ方向から見て前記正極板３０Ｐの角Ｃに重なる突部４５を有する。【選択図】図１１
