PROBLEM TO BE SOLVED: To realize practicability in manufacturing a thin product of magnesium alloy by plastic working. SOLUTION: The device is equipped with a preheating mechanism A and a press type continuous working mechanism B for a magnesium alloy sheet (workpiece) C. In the device, continuous working dies 2 to be loaded on a die base 3a are brought into contact with a heat plate 4 having a suitable heat source while a heat insulation part 5 is interposed between the die and the base, and then, the dies are incorporated in a state controllable at a desired temperature. With the workpiece preliminarily warmed at a prescribed temperature, and with each die of the continuous working dies raised to the prescribed temperature, a specified plastic working is continuously and successively performed on the preheated workpiece.
