Zusammenfassung:To provide a stitch connection structure suitable for example for cathode foils containing a carbon layer.SOLUTION: A cathode foil (6) includes a base foil (12) and a carbon layer (14) formed on the base foil. A pull-out terminal (4) includes a terminal portion (18) and a terminal piece (20) extending from the terminal portion, and a stitch connection portion (10) is connected to the cathode foil by sandwiching the cathode foil between the terminal portion and the terminal piece. The pull-out terminal includes a metal surface portion (28) and a hardened surface portion (30) that is harder than the metal surface portion, the metal surface portion is in contact with the substrate foil in a first region (36) of the stitch connection portion, and the hardened surface portion is laminated to the carbon layer in a second region (38) of the stitch connection portion.SELECTED DRAWING: Figure 1 【課題】 本開示は、たとえばカーボン層を含む陰極箔に適したステッチ接続構造を提供することを目的とする。【解決手段】 陰極箔(6)は、基材箔(12)と、該基材箔上に形成されたカーボン層(14)とを含む。引き出し端子(4)は、端子部(18)と前記端子部から伸びる端子片(20)とを含み、前記端子部および前記端子片の間に前記陰極箔を挟むことによりステッチ接続部(10)で前記陰極箔に接続される。前記引出し端子は、金属表面部(28)と該金属表面部よりも硬い硬化表面部(30)とを有し、前記金属表面部は、前記ステッチ接続部の第一領域(36)で前記基材箔と接触し、前記硬化表面部は、前記ステッチ接続部の第二領域(38)で前記カーボン層に積層する。【選択図】 図1
