Zusammenfassung:	PROBLEM TO BE SOLVED: To facilitate centering work and to precisely grind by arranging a centering reference face at the time of grinding to have a coaxial peripheral shape to the inner periphery of a die and making the centering reference face into a non-contact state with other parts at the time of can manufacturing. SOLUTION: A difference in level part 6 is arranged in a die outer peripheral part 5 of a case 2 of an ironing die 1, a centering reference face 7, which has a diameter smaller than the die outer peripheral part 5 and is parallel to an axial line X, is formed in the difference in level part 6. The diameter dimension of the centering reference face 7 is desirably finished with precision of
