FILM LAMINATE METAL SHEET, SUBSTRATE FOR FLEXIBLE DEVICES, AND SUBSTRATE FOR ORGANIC EL DEVICES

A film-laminated metal sheet according to the present invention is coated with a resin film on at least one surface. An arithmetic mean height Sa0 of a surface of the resin film is 3.0 nm or smaller, and when an arithmetic mean height of the surface of the resin film after thermal treatment at 100°C is Sa1, an arithmetic mean height change ratio {(Sa1/Sa0) × 100} is 80% or more and 120% or less. A ten-point height S10z0 of the surface of the resin film may be 50 nm or smaller. When a ten-point height of the surface of the resin film after thermal treatment at 100°C is S10z1, a ten-point height change ratio {(S10z1/S10z0) × 100} may be 80% or more and 120% or less.
