Abstract:
A coated tool may include a base member including a first surface, and a coating layer. The coating layer may include a plurality of voids located side by side in a first layer in a direction along an interface, which is a boundary between the first layer and a second layer. The second layer may include a lower layer part and an upper layer part, and an angle formed by a normal line of (001) surface of the constituent particles with respect to a cross section of the second layer is an orientation difference, the lower layer part of the second layer includes a ratio of the particles whose orientation difference is 10° or more of 50% or more, and the upper layer part of the second layer includes a ratio of the particles whose orientation difference is 10° or less of 80% or more.
