PROBLEM TO BE SOLVED: To provide an anti-staining precoated aluminum sheet good in bending processability. SOLUTION: In the anti-staining precoated aluminum sheet manufactured by forming a chemical forming film on the surface of an aluminum sheet and further forming a two-layered coating film on the chemical forming film, coating containing a polyester resin, of which the number average molecular weight is 20,000-30,000 and the multidispersibility is 2-10, as a base resin is baked to form an undercoating layer with a film thickness of 3-13μm and coating containing a base resin comprising an acrylic resin, colloidal silica, a silicone compound containing an alkoxy group and at least one kind of a pigment or dye is baked to form a topcoating layer with a film thickness of 8-20μm.
