To provide a press forming die having a protection film formed by the PVD process and having a high resistance to seizure, and a method for manufacturing a press forming die protection film.

In the press forming die, a protection film to prevent seizure upon press forming is formed at least on a molding surface that comes into contact with an object to be molded. This protection film is formed by the PVD process and when an arbitrarily selected section picked up from the surface of the protection film is divided into a plurality of individual sections and the number of divisions is taken to be N, and the slope of the surface at the n-th division point from the end of the selected section is taken to be (dZ_n/dX_n), a root-mean-square value RΔq calculated from Mathematical expression 1 is 0.032 or less.
