Provided is a hard coating film which is hardly adhered to a soft metal and is suitable for the coating of, for example, the surface of a hot pressing mold that may be in contact with the soft metal. The hard coating film is characterized in that, on the surface of the hard coating film, the arithmetic average roughness (Ra) is 0.05 µm or less and the average number of pin holes each having an equivalent circle diameter of 1 µm or more is 5 or less per field when at least five fields each having a size of 45 x 65 µm are observed on a scanning electron microscope at 2000-fold magnification. |
