徴とするクラツド式鉛蓄電池。[Claims for Utility Model Registration] An electrode plate group in which a negative electrode plate having an ear portion at the upper end and a clad positive electrode plate are laminated with a separator interposed therebetween is housed in a battery case, and a negative electrode protrudes from the upper end of the electrode plate group. In a clad lead-acid battery in which the ears of the plate group and the ears of the positive electrode plate group are connected by a negative electrode strap and a positive electrode strap, respectively, a short-circuit prevention plate is attached to the ear of the negative electrode plate group, and the aforementioned short-circuit prevention is achieved. The plate includes a horizontal plate part that has an ear insertion groove through which each ear of the negative electrode plate group is inserted and is arranged parallel to the upper end surface of the electrode plate group, and an end of the horizontal plate part on the positive electrode strap side. a first inclined plate part that extends upwardly from the horizontal plate part; and a second inclined plate part that extends downwardly from the end of the horizontal plate part opposite to the positive electrode strap toward the side wall of the battery case. A closed-type lead-acid battery characterized by having:
