    Abstract: This application provides a current collecting member, a secondary battery, and a method for manufacturing a secondary battery. The current collecting member includes a substrate and a support plate, the substrate is disposed on a side of a body of the electrode assembly in the transverse direction and extends in a direction perpendicular to the transverse direction, the support plate extends from an outer end of the substrate in the longitudinal direction and folds back to a side of the substrate farther from the body. The support plate includes a bending portion and a connecting portion, the bending portion is connected to the substrate and bent into an arc shape, and the connecting portion extends from an end of the bending portion farther from the substrate; and a first tab of the electrode assembly is connected to the connecting portion and bent along a surface of the bending portion.
