Abstract
A surface metal film material including, in this order, a substrate, a polymer layer that receives a plating catalyst or a precursor thereof, and a metal film formed by plating, wherein, when x μm represents surface roughness (Ra) at the interface between the substrate and the polymer layer, and y μm represents surface roughness (Ra) at the interface between the polymer layer and the metal film, x>y and 5 μm>x>0.1 μm, and wherein, when T μm represents a thickness of the polymer layer, T and x satisfy the relationship 2x≦T.
