PURPOSE: A method of deep drawing magnesium material that has superior in environmental compatibility and energy saving properties is provided. This method has advantages in that it can be applied not only to a general press working of hard metals such as magnesium, but also to deep draw forming of hard metals without using a large-scale instrument. CONSTITUTION: The deep drawing method uses a die having a male mold(1) with a convex portion, and a female mold having a concave surface. In the method of the invention, a mounting table(3) is placed between the male mold and the female mold for supporting a magnesium plate(5), and a layer of a plurality of thin resin films is placed on the magnesium plate. Further, a central portion of the magnesium plate(5) is kept in contact with the convex portion of the male mold, and the concave surface of the female mold is moved to cooperate with the convex portion of the male mold so that deep draw forming of the magnesium plate is achieved.
