Classification: CPC B  C  Y | IPC B  C

Claim 0:
1. A coated tool, comprising:
a base member comprising a first surface; and
a coating layer located at least on the first surface of the base member,
wherein
the coating layer comprises:
a first layer located on the first surface and comprising a titanium compound, and
a second layer located on and in contact with the first layer and comprising aluminum oxide;

the second layer comprises an orientation coefficient Tc(0012) of 3.0 or more by X-ray diffraction analysis; and
the coating layer further comprises a plurality of voids located in a direction along a boundary between the first layer and the second layer, and
an average value of widths of the voids in the direction along the boundary is less than an average value of distances between respective voids of the plurality of voids adjacent to each other in a cross section orthogonal to the first surface and
an average value of widths of the respective voids in a direction parallel to the first surface is greater than an average value of heights of the respective voids in a direction orthogonal to the first surface in the cross section orthogonal to the first surface.
