Abstract
A coated tool may include a base member and a coating layer. The coating layer may include a Ti(C, N) layer, and an AlOlayer covering the Ti(C, N) layer. The Ti(C, N) layer may include a void region including a plurality of voids along an interface between the Ti(C, N) layer and the AlOlayer. An average value of widths of the voids may be less than an average value of distances between the voids adjacent to each other. The Ti(C, N) layer may include a first Ti(C, N) layer located closer to the base member than the void region. An average atomic ratio of carbon to the sum of carbon and nitrogen (C/(C+N)) in the first Ti(C, N) layer may be 0.50 to 0.65.
