description Provided is a method for producing a workpiece made of nano-crystal soft magnetic material, capable of efficiently producing a workpiece. The method sandwiches at least one metal sheet made of amorphous soft magnetic material between a punch and a die and punches the workpiece from the metal sheet to produce the workpiece. The method heats the punch to a crystallization starting temperature or higher at which the amorphous soft magnetic material crystallizes into nano-crystal soft magnetic material. The method includes a step of punching the workpiece from the metal sheet while heating the metal sheet with the punch and a step of crystallizing the amorphous soft magnetic material of the workpiece into nano-crystal soft magnetic material by making the workpiece after punched absorbed on the punch.
