PROBLEM TO BE SOLVED: To provide an Al-Mg-Si alloy sheet which has excellent bending workability such as flat hemming in particular, and further has the other properties required for a panel, and to provide a production method thereof. SOLUTION: The Al-Mg-Si aluminum alloy sheet comprising 0.4 to 1.3% Si, 0.2 to 1.2% Mg, 0.01 to 0.65% Mn, and 0.001 to 1.0% Cu, and the balance Al with inevitable impurities. The ratio of the integrated intensity in the ä200} plane in the surface of the aluminum alloy sheet is≥50%, and the ratio of the total integrated intensity in the ä200} plane and the ä400} plane is≥60%.
