PROBLEM TO BE SOLVED: To provide a surface-treated aluminum material which is excellent in bondability with a polyamide resin and has good productivity and economical efficiency even when formed into a large-sized member and a method for producing the same, and to provide a composite molding using the surface-treated aluminum material and a method for producing the same.SOLUTION: There is provided a surface-treated aluminum material which is the surface-treated aluminum material for insert molding combined with a resin containing polyamide, and has a base material containing aluminum as a main component and a resin film laminated directly on the base material or through a base film, where the resin film contains polyester amide having a hydroxyl group or an amino group at a terminal end as the main component. The surface-treated aluminum material has the base film, and the base film is a chemical conversion film, a plating film or a combination thereof. An average thickness of the resin film is preferably 10 μm or more and 500 μm or less per one surface.SELECTED DRAWING: Figure 1 |
