PROBLEM TO BE SOLVED: To provide a hard film-coated tool that involves an improvement in the oxidation resistance and coefficient of friction of its hard film and is applicable to dry and high-speed cutting. SOLUTION: The hard film-coated tool has a hard film of an at least two- alternated lamination of an A layer having chemical composition represented by (Ti1-a-bVaSib)(NxO1-x) wherein 0<=a<=0.5, 0.1<=b<=0.7 and 0.5<=x<=0.999, and a B layer having chemical composition represented by (TiAl)(NyO1-y) wherein 0.5<=y<=0.999.
