The die 5 for drawing has a cutting edge 12 on the stepped part 11, and the punch 3 has a concavity on the surface, and has a cutting edge projected from the plate thickness of a work W in the concavity 19. Shearing is performed during the course of drawing in cooperation with the cutting edge 12 blank holding the work W by the end face 16 and cutting edge 20.
