Zusammenfassung:	A coated aluminum sheet (1) includes an aluminum alloy sheet (3) including a first surface (3a) and a second surface (3b) situated opposite to the first surface (3a) and first and second coating film (5, 7) formed on the first and second surfaces (3a, 3b), respectively. The first and second coating films (5, 7) each have a mass of 0.1 to 20 g/m2 per unit area. The first coating film (5) 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 (7) contains 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 (5, 7) 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 (7) is 10 mg/m2 or less in amount. The most suitable drawing: FIG. 1.
