To provide a bipolar lead-acid battery that facilitates execution of alignment between adjacent frame units.SOLUTION: A bipolar lead-acid battery has: a plurality of cell members 150 that each include a positive electrode 151 having an active material layer 103 for a positive electrode, a negative electrode 152 having an active material layer 104 for a negative electrode, and an electrolyte layer 105 interposed between the positive electrode and the negative electrode, and that are arranged laminated at an interval; and a plurality of frame units that form a plurality of spaces for individually accommodating the plurality of cell members, and the cell members are electrically connected in series with one another. A first connection part 141 is formed on one of the pair of frame units adjacent in a lamination direction, and a second connection unit 142 that can be connected with the first connection part is formed on the other of the pair of frame units adjacent in the lamination direction.SELECTED DRAWING: Figure 2 【課題】隣接するフレームユニットの間の位置合わせを容易に行うことができる双極型鉛蓄電池を提供する。【解決手段】双極型鉛蓄電池は、正極用活物質層１０３を有する正極１５１、負極用活物質層１０４を有する負極１５２、および正極と負極との間に介在する電解層１０５を備え、間隔を開けて積層配置された、複数のセル部材１５０と、複数のセル部材を個別に収容する複数の空間を形成する、複数のフレームユニットと、を有し、セル部材同士が直列に電気的に接続されている。積層方向で隣接する一対のフレームユニットの一方に、第一の連結部１４１が形成され、積層方向で隣接する一対のフレームユニットの他方に、第一の連結部と連結可能に構成された第二の連結部１４２が形成されている。【選択図】図２
