Beschreibung
Zusammenfassung:	[Object]A pressing die and a press working method that can achieve both facilitation of management of an appropriate clearance and working durability at a high level are provided.[Solving Means]The pressing die of the present invention is a pressing die for press working a metal material using a punch part and a die part. A working surface of one of the punch part and the die part is coated with a diamond film the working surface contacting with the metal material. A working surface of the other one of the punch part and the die part is coated with a surface treatment film having a Vickers hardness of 8000 Hv or less the working surface contacting with the metal material.
