    Abstract: To provide a method for producing a magnesium alloy plate which can be suitably employed for producing a magnesium alloy plate excellent in the plastic workability such as press workability. A method for producing a magnesium alloy plate according to the present invention relates to a method for rolling a magnesium alloy raw sheet by a rolling roll. The rolling includes a controlled rolling which is carried out under the following conditions (1) and (2), where M (mass %) represents an aluminum content of a magnesium alloy constituting the raw sheet: (1) a surface temperature of the magnesium alloy raw sheet (Tb, °C) immediately before the insertion to the rolling roll satisfying the following formula: 8.33 x M + 135
