PROBLEM TO BE SOLVED: To provide a hard film capable of imparting excellent wear resistance to a coating film-formed body. SOLUTION: The hard film is composed of (Ti<SB>a</SB>Cr<SB>b</SB>Al<SB>c</SB>L<SB>d</SB>) (BxCyNz) (wherein L denotes at least one of Si and Y, and when a, b, c, d, x, y, and z each denote the atomic ratio, the composition satisfies 0.1≤<0.3; 0.3<b<0.6; 0.2≤c<0.35; 0.01≤d<0.1; a+b+c+d=1; x≤0.1; y≤0.1; 0.8≤z≤1; and x+y+z=1).
