A hard coating film having wear resistance superior to conventional TiAlN coating films, oxide coating films, and the like. The hard coating film of the present invention has a component composition represented by one of the following two formulas: (TiaAlbSic)Ox, wherein 0.3≦a≦0.7, 0.3≦b≦0.7, 0≦c≦0.2, a+b+c=1, and 0.8≦[x/(2a+1.5b+2c)]≦1.2; and (TiaCrdAlbSic)Ox, wherein 0.05≦a≦0.4, 0.1≦d≦0.85, 0≦b≦0.7, 0≦c≦0.2, a+b+c+d=1, and 0.8≦[x/(2a+1.5d+1.5b+2c)]≦1.2; where variables a, d, b, and c denote the atomic ratios of Ti, Cr, Al, and Si respectively, and variable x indicates the atomic ratio of O.
