PROBLEM TO BE SOLVED: To provide a magnesium alloy rolled sheet which is reduced in its anisotropy, has satisfactory formability and is high in latness, and to provide a method for producing the magnesium alloy rolled sheet. SOLUTION: In this method, the molten metal of a magnesium alloy having a composition containing, by mass, 1 to 11% Al,≤2.0% Zn and 0.1 to 0.5% Mn, and the balance Mg with inevitable impurities is subjected to continuous casting, so as to be a beltlike sheet with a sheet thickness of 3 to 10 mm, is thereafter subjected to homogenizing heat treatment, and is subsequently subjected to hot and warm, or hot or warm cross roll rolling, thereby producing the magnesium alloy rolled sheet reduced in anisotropy and having excellent press formability.
