Coated tool and cutting tool

A coated tool, comprising:

• a base member comprising a first surface;
• and
• a coating layer located on the first surface,
• wherein
• the base member comprises a hard phase with tungsten carbide particles, and a binder phase comprising cobalt, nickel, or combinations thereof;
• island portions each comprising 70 area % or more of the binder phase and having an equivalent circle diameter of 10 μm or more are scattered on the first surface;
• the coating layer comprises:
• a first layer comprising a titanium compound and located on the first surface, and
• a second layer comprising aluminum oxide and located on and in contact with the first layer;
• and
• the coating layer comprises a plurality of voids located on the first layer in a cross section orthogonal to the first surface so as to be arranged side by side in a direction along a boundary between the first layer and the second layer;
• an average value of widths of respective voids of the plurality of voids in the direction along the boundary is less than an average value of distances between the respective voids adjacent to each other;
• and in the cross section orthogonal to the first surface, 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.
