PROBLEM TO BE SOLVED: To provide a cheap wrought magnesium sheet excellent in formability especially press formability, and its manufacturing method. SOLUTION: A rolled Mg alloy sheet contains 1.0-2.0wt% Al, 0.5-2.0wt% Zn, 0.05-1.0wt%, and the remainder Mg and inevitable impurities, and the rolled Mg alloy sheet is heat treated after rolled, and an X-ray intensity ratio [X-ray intensity in (0002) plane]/[X-ray intensity in (101(upper bar) 1)] is 1.0-3.5, and an yield strength parallel to and perpendicular to rolling direction is 100-300MPa, and an average crystal grain diameter is 3-100μm, and these are the characteristics of the wrought magnesium sheet which is excellent in formability, and its manufacturing method.
