Abstract
A coated tool includes a base body and a coating layer located on a surface of the base body. The coating layer includes at least a titanium carbonitride layer and an aluminum oxide layer having an α-type crystal structure. In an X-ray diffraction analysis of the aluminum oxide layer, peaks related to AlOappear in a wavenumber range of 416-425 cm(around 420 cm) of a Raman spectrum obtainable by irradiating an Ar laser beam having a wavelength of 514.53 nm from a cross section of the aluminum oxide layer. When a base body-side peak to be detected by measurement at the base body side portion of the aluminum oxide layer is compared with a surface-side peak to be detected by measurement at the surface side-portion of the aluminum oxide layer, the peak is located at a wavenumber on a lower angle side than the peak.
