PROBLEM TO BE SOLVED: To provide a wear-resistant hard film-coated tool. SOLUTION: A base is coated with a first hard film formed of TiC<SB>(1-e</SB>)N<SB>e</SB>and having an N atomic ratio e of 0.5≤e≤1. The first hard film is coated with a second hard film formed of (Al<SB>a</SB>Ti<SB>b</SB>Cr<SB>c</SB>)(C<SB>1-d</SB>N<SB>d</SB>) where 0.2≤a≤0.45, 0.5≤b≤0.75, 0.02≤c≤0.2, a+b+c=1, and 0.5≤d≤1. Also, the surface of the second hard film is subjected to X-ray diffraction, and the peak height of a crystal face 200 is h (200) and the surface of a crystal face 111 is h (111), 1≤h(200)/h(111)≤10.
