A coated tool may include a base member including a first surface, and a coating layer located at least on the first surface of the base member. The coating layer may include a first layer located on the first surface and including a titanium compound, and a second layer contactedly located on the first layer and including aluminum oxide. The second layer may include an orientation coefficient Tc(0012) of 3.0 or more by X-ray diffraction analysis. The coating layer may include a plurality of voids located in a direction along an interface between the first layer and the second layer, and an average value of widths of the voids in a direction along the interface is smaller than an average value of distances between the voids adjacent to each other in a cross section orthogonal to the first surface.
