Disclosed are a hard film and a method useful for manufacturing the hard film wherein the hard film is obviously excellent in wear resistance, and exhibits excellent oxidation resistance even under a condition where hot heat generation tends to occur due to friction heating, consequently exhibits excellent properties compared with a usual hard-film including TiAlN, TiCrAlN, TiCrAlSiBN, CrAlSiBN, or NbCrAlSiBN. The hard film includes (M)aCrbAlcSidBeYfZ (however, M is at least one element selected from a group 4A element, a group 5A element, and a group 6A element (except for Cr) in the periodic table, and Z shows one of N, CN, NO and CNO), wherein a+b+c+d+e+f=1, and 0
