Abstract:
A laminated resin film includes: a resin layer; and a Cu film having on one surface or both surfaces of the resin layer, in which in the Cu film, an orientation index of a plane is 0.15 or more according to a Lotgering method, a half-width of an X-ray diffraction peak obtained by X-ray diffraction measurement of the plane is 0.3° or less, and Expression (1) is satisfied.
y>3.75x−0.675 Expression (1)
(in Expression (1), Y is the orientation index of the plane in the Cu film according to the Lotgering method, and x is the half-width of the X-ray diffraction peak obtained by the X-ray diffraction measurement of the plane in the Cu film.)
