Zusammenfassung:To provide a cell laminate in which tab leads of a plurality of laminated cells and a conductive connection member can be connected in a space-saving manner.SOLUTION: A cell laminate 1 includes: a plurality of laminated cells 2 which are laminated. In each laminated cell 2, tab leads 21, 22 of the plurality of laminated cells 2 are electrically connected to each other via a conductive connection member 30 having a plate shape. The tab leads 21, 22 connected to the conductive connection member 30 have respective linear portions 211, 221 extending linearly in a direction perpendicular to a lamination direction from a sealing portion 20 to respective tip ends 21a, 22a. The tip ends 21a, 22a of the respective tab leads 21, 22 are bonded in close contact with the conductive connection member 30 by a surface, of the surface of the conductive connection member 30, which is parallel to an extension direction of the respective tab leads 21, 22 at an inside connection portion 47 located inside the conductive connection member 30 in the lamination direction.SELECTED DRAWING: Figure 3 【課題】複数のラミネート型セルのタブリードと導電接続部材との接続を省スペースで行うことができるセル積層体を提供する。【解決手段】セル積層体1は、積層された複数のラミネート型セル2を備える。各ラミネート型セル2は、複数のラミネート型セル2のタブリード21、22は、板形状を有する導電接続部材30を介して互いに電気的に接続されている。導電接続部材30に接続されたタブリード21、22は、シール部20から先端部21a、22aまで積層方向と直交する方向に直線状に延出する直線部211、221を有する。各タブリード21、22の先端部21a、22aは、積層方向で導電接続部材30の内側に位置する内側接続部分47において、導電接続部材30の表面のうちタブリード21、22の延出方向に平行な面で導電接続部材30に密着して接合されている。【選択図】図3
