A1

A plurality of laminate cells (10) are layered on a tray (30) in a two-layer structure comprising a first layer and a second layer. The first layer includes at least two laminate cells (10). At least two laminate cells (10) in the first layer are lined up in a first direction X at a fixed pitch such that the sides from which a positive electrode tab (11p) and a negative electrode tab (11n) lead out form a straight line. The laminate cells (10) constituting the second layer are offset in the first direction from the laminate cells (10) constituting the first layer such that tabs (11p, 11n) of opposite polarities are facing in the layering direction. The polar-opposite tabs (11p, 11n) facing the upper and lower layers are electrically connected such that the plurality of laminate cells (10) are connected in series.
