To provide a method for producing a magnesium alloy member which is inexpensive and has excellent forgeability.
Disclosed is a method for producing a magnesium alloy member comprising: a stage where Mg, Zn, Y, and Zr in the rage of 0.1 to 0.7 wt.% to the whole quantity are melted, the obtained molten metal M is continuously fed to a mold 3 with a prescribed shape, is cooled inside the mold 3 and is taken out, thus a cast body Ma composed of a magnesium alloy comprising Zn and Y and also having a crystal grain size in the range of 50 to 150 m is obtained; and a stage where the cast body is heated at a temperature in the range of 350 to 500C, and is forged so as to obtain a forged body to be the magnesium alloy member. The relative strain quantity applied by the forging lies in the range of 1.1 to 5.0.
