A coated cutting insert according to the present invention includes a substrate, a base layer formed on the substrate, and an indicating layer formed on a part of the base layer. The base layer exhibits a color different from that of the indicating layer. The indicating layer is formed on the base layer, in at least a part of a surface including a cutting-edge portion and a rake face except for a flank face. When a surface relative roughness Ra of a breaker recess portion or a land portion of the rake face is set to Aμm and a surface relative roughness Ra of the flank face is set to Bμm, relation of B/A≦is established.
