PROBLEM TO BE SOLVED: To provide a malleable magnesium sheet excellent in formability, especially in cold press formability, and its manufacturing method. SOLUTION: An extruded Mg alloy plate which contains 1.0-2.0wt% Al, 0.5-2.0wt% Zn and 0.05-1.0wt% Mn and the balance Mg with inevitable impurities, is rolled followed by heat treatment to form the malleable magnesium sheet, wherein an X-ray intensity ratio in an X-ray diffraction [the X-ray intensity in (0002) face]/[the X-ray intensity in (101<SP>-</SP>1) face] is 1.0-3.5, and a yield strength in a direction parallel to and perpendicular to a rolling direction is 130-300MPa, and an average crystal grain diameter is 3-100μm.
