Zusammenfassung:To provide a laminated cell and battery pack that can appropriately lay out detection lines and can be miniaturized.SOLUTION: A laminated cell 10 includes an electrode body 11, tab leads 12 and 13 connected to the electrode body 11, and an exterior body 20 that houses the electrode body 11 such that the tab leads 12 and 13 are exposed, and is made of a laminate film. The exterior body 20 includes an electrode body housing portion 23 that houses the electrode body 11, and an ear portion 24 extending outside the electrode body housing portion 23. A temperature detection line 16 and at least one of voltage detection lines 14 and 15 are arranged in a folded portion 25 obtained by folding back the ear portion 24, and is arranged so as to overlap with the electrode body housing portion 23.SELECTED DRAWING: Figure 1 【課題】検出線を適切にレイアウトすることができ、小型化が可能なラミネート型セル及びバッテリパックを提供する。【解決手段】ラミネート型セル10は、電極体11と、電極体11に接続されるタブリード12、13と、タブリード12、13が露出するよう電極体11を収容し、ラミネートフィルムから構成される外装体20と、を備える。外装体20は、電極体11を収容する電極体収容部23と、電極体収容部23の外側に延設される耳部24と、を備える。温度検出線16及び電圧検出線14、15の少なくとも一方の検出線が、耳部24を折り返した折り返し部25に配置され且つ電極体収容部23と重なるように配置される。【選択図】図1
