Beschreibung
Zusammenfassung:	A coated aluminum sheet includes an aluminum alloy sheet including a first surface and a second surface situated opposite to the first surface and first and second coating films formed on the first and second surfaces, respectively. The first and second coating films each have a mass of 0.1 to 20 g/m2 per unit area. The first coating film includes 0.1 to 1.5% by mass of a polyethylene wax and 0.1 to 1.5% by mass of a carnauba wax. The second coating film includes 0.4 to 0.8% by mass of a polyethylene wax and 0.4 to 0.8% by mass of a carnauba wax. Respective contents of another wax in the first and second coating films are 1.5% by mass or less and 0.7% by mass or less respectively. Post-lubrication including a petrolatum wax on the second coating film is 10 mg/m2 or less in amount.
