Abstract: A current collector including: a resin layer having first and second surfaces on opposites sides; and a metal layer including copper. The metal layer includes a first metal layer located on a side of the first surface of the resin layer. A yield stress σY1 of the current collector is smaller than a tensile fracture stress σB2 of the resin layer. The yield stress σY1 [MPa] is obtained by expressions (1) and (2) from a resin layer yield stress σY2 [MPa], a resin layer thickness D2 [μm], a yield stress σY3 [MPa] of the metal layer, and a thickness D3 [μm] of the metal layer: σ ⁢ Y ⁢ 1 = A × σ ⁢ Y ⁢ 3 + ( 1 - A ) × σ ⁢ Y ⁢ 2 ( 1 ) A = D ⁢ 3 / ( D ⁢ 2 + D ⁢ 3 ) . ( 2 ) The yield stress σY3 [MPa] is obtained by the following expression (3) from a half-value width β [°] of an X-ray diffraction peak having the highest intensity in an X-ray diffraction pattern of the metal layer σ ⁢ Y ⁢ 3 = ( - 103 + 1 ⁢ 6 ⁢ 44 × √ β ) .
