Abstract
A film-laminated metal sheet satisfies smoothness, heat resistance, flexibility, and gas barrier properties and has a low environmental burden and excellent productivity and a method produces the metal sheet, a substrate for flexible electronics, and an organic EL substrate. The film-laminated metal sheet has at least one surface covered with a resin film. The arithmetic average roughness Sa of a surface of the resin film is 0.030 μm or less. The maximum peak height Sp of the surface of the resin film is 0.30 μm or less. The maximum valley depth Sv of the surface of the resin film is 1.0 μm or less.
