Abstract

The purpose of the present invention is to provide a coated metal mold having superior durability and adhesion resistance over a usage range from cold to warm/hot; and a method for manufacturing the coated metal mold. The coated metal mold is characterized by having a hard coating on a surface, wherein the hard coating includes an A layer formed from a nitride and having a film thickness not smaller than 5 μm, and a B layer formed of a diamond-like carbon coating, the B layer is disposed closer to the outer surface side than the A layer, the surface of the B layer has an arithmetic mean roughness Ra≤0.2 μm, a maximum height Rz≤2.0 μm, and a skewness Rsk<0.
