1. A coated tool, comprising:
a base body; and a coating layer located on a surface of the base body, wherein the coating layer comprises at least a titanium carbonitride layer and an aluminum oxide layer having an α-type crystal structure, and the titanium carbonitride layer is located closer to the base body than the aluminum oxide layer, and wherein, of peaks related to Al2O3 appearing in a wavenumber range of 416-425 cm−1 (around 420 cm−1) of a Raman spectrum obtainable by irradiating an Ar laser beam having a wavelength of 514.53 nm to the aluminum oxide layer in a cross section of the coated tool, a base body-side peak to be detected by measurement at a base body-side portion of the aluminum oxide layer is taken as “p”, and a surface-side peak to be detected by measurement at a surface-side portion of the aluminum oxide layer is taken as “q”, and, when a comparison is made between “p” and “q”, the peak “q” is located at a wavenumber on a lower angle side than the peak “p”. |
