Abstract
A coated tool includes a base body and a coating film. The coated tool has a first surface with a rake face, a second surface with a flank face, and a third surface located between the first surface and the second surface and being a C surface or an R surface. The coating film includes a first coating film located on the first surface and/or a second coating film located on the second surface, and a third coating film located on the third surface. A wavenumber of a maximum Raman peak of the first coating film is a first wavenumber, a wavenumber of a maximum Raman peak of the second coating film is a second wavenumber, and a wavenumber of the maximum Raman peak of the third coating film is a third wavenumber. The third wavenumber is smaller than the first wavenumber and the second wavenumber.
