A hard coating film formed on a surface of a predetermined member and having excellent wear resistance and adhesion resistance, the hard coating film includes: a three-layer structure composed of a third layer formed in contact with the surface of the predetermined member, a second layer formed on the third layer, and a first layer formed on the second layer to constitute the surface; the first layer being made of (Cr1-a-bBa(SiC)b)(CcOdN1-c-d) [provided that SiC is silicon carbide, and a, b, c and d are atomic ratios in ranges of 0≰a≰0.2, 0.01≰b≰0.2, 0≰c≰0.5 and 0≰d≰0.3, respectively; the second layer being made of AlCrN or AlCrDN [provided that D includes either one kind of elements of a Group IVa, a Group Va and a Group VIa (except Cr) of a Periodic Table of Elements and Y, or SiC (silicon carbide)]; and the third layer being made of nitride, carbon nitride or carbide of metals including elements of one kind or more kinds of Al, Ti, Zr, Hf, V, Nb, Ta, Cr and W.
