To provide a positive electrode for a lead-acid battery capable of achieving sufficient discharge and recharging even after long-term stopping as well as high durability because of excellent adhesiveness between a positive electrode collector and a positive electrode active material.SOLUTION: A positive electrode collector, a carbon-containing layer and a positive electrode active material layer are arranged in this order. The carbon-containing layer contains a conductive carbon material and a polymer compound, and the positive electrode active material layer contains lead dioxide.SELECTED DRAWING: None 【課題】十分に放電し長期間停止した後でも再度充電することができ、且つ、正極集電体と正極活物質との接着性に優れるため耐久性が高い鉛蓄電池用正極を提供する。【解決手段】正極集電体、炭素含有層及び正極活物質層がこの順で配置されており、前記炭素含有層は、導電性炭素材料及び高分子化合物を含有し、前記正極活物質層は、二酸化鉛を含有する、鉛蓄電池用正極。【選択図】なし
