摘要：
A current collector for a nonaqueous solvent secondary battery, which includes: a first metal layer; and a second metal layer stacked on a surface of the first metal layer, is composed so that a Young's modulus (E1), Vickers hardness (Hv1) and thickness (T1) of the first metal layer and a Young's modulus (E2), Vickers hardness (Hv2) and thickness (T2) of the second metal layer can satisfy the following Expression: (E1>E2 or Hv1>Hv2); and T1
