Abstract
A coated tool may include a base member and a coating layer located on the base member. The coating layer may include a plurality of AlTi layers including aluminum and titanium as a main component, and a plurality of AlCr layers including aluminum and chromium as a main component. The AlTi layers and the AlCr layers may be located alternately one upon another. The plurality of AlTi layers may include a first AlTi layer and a second AlTi layer located farther away from the base member than the first AlTi layer. Each of the plurality of AlTi layers may further include chromium, and a content ratio of chromium in the second AlTi layer may be higher than a content ratio of chromium in the first AlTi layer.
