Abstract:
A surface-coated cutting tool of the present invention includes a base material and a coating formed on the base material, the coating includes one or two or more layers, a layer among these layers that abuts on the base material is a TiN layer, the TiN layer contains at least one element together with TiN, the element has a concentration distribution in a thickness direction of the TiN layer, and the concentration distribution includes a region where the concentration of the element decreases in a direction from the base material toward a surface of the coating.
