Abstract
A resin film-laminated metal sheet includes a metal sheet and thermoplastic resin films that are fused to both surfaces of the metal sheet, the metal sheet is a steel sheet having a thickness of 0.08 mm or more or an aluminum sheet having a thickness of 0.15 mm or more, and, when a surface of the thermoplastic resin film opposite to a surface that is fused to the metal sheet is defined as a first surface, the surface tension on the first surface in at least one of the thermoplastic resin films is 50 mN/m or less, the surface tension on the surface that is fused to the metal sheet is 36 mN/m or more, and the amount of a wax attached to the first surface is more than 0 mg/mand 5.00 mg/mor less.
