Zusammenfassung:	The present invention relates to a lead tab, and a pouch-type battery comprising the same. A lead tab according to an embodiment of the present invention includes a metal and a film applied to at least one surface of the metal, wherein the metal includes a first metal layer, a second metal layer on the first metal layer, a third metal layer on the second metal layer, and an organic layer on the third metal layer, wherein at least a part of the third metal layer is applied by electroless plating on the second metal layer. Therefore, the present invention can improve a film adhesion of a metal and corrosion resistance to an electrolyte solution in a pouch-type battery. La présente invention porte sur une languette de connexion et une batterie de type poche la comprenant. Une languette de connexion selon un mode de réalisation de la présente invention comprend un métal et un film appliqué sur au moins une surface du métal, le métal comprenant une première couche métallique, une seconde couche métallique sur la première couche métallique, une troisième couche métallique sur la seconde couche métallique, et une couche organique sur la troisième couche métallique, au moins une partie de la troisième couche métallique étant appliquée par dépôt autocatalytique sur la seconde couche métallique. Par conséquent, la présente invention peut améliorer une adhérence de film d'un métal et une résistance à la corrosion à une solution électrolytique dans une batterie de type poche. 본 발명은 리드 탭 및 이를 구비하는 파우치형 배터리에 관한 것이다. 본 발명의 실시예에 따른 리드 탭은, 리드 탭은, 메탈과, 메탈의 적어도 일면에 도포되는 필름을 구비하고, 메탈은, 제1 금속층과, 제1 금속층 상의 제2 금속층과, 제2 금속층 상의 제3 금속층과, 제3 금속층 상의 유기층을 포함하고, 제3 금속층의 적어도 일부는, 제2 금속층 상에 도포시, 무전해 도금으로 도포된다. 이에 의해, 메탈의 필름 부착력을 향상시키고, 파우치형 배터리 내의 전해액에 대한 내식성을 향상시킬 수 있게 된다.
