PROBLEM TO BE SOLVED: To provide an aluminum alloy sheet excellent in formability and corrosion resistance, furthermore having sufficient strength after coating/baking and suitable for an automotive body. SOLUTION: Relating to an Al-Mg-Si aluminum alloy sheet, its thermal analysis curve has an endothermic peak equivalent to that in Mg-Si cluster melting. The alloy sheet preferably has a compsn. contg., by mass, 0.2 to 1.1% Mg and 0.6 to 1.7% Si, moreover contg. one or more kinds among <=0.15% Ti, <=0.05% B, <=0.4% Mn, <=0.3% Fe and <=1.0% Zn, and the balance Al with inevitable impurities.
