Surface Coated Member and Manufacturing Method Thereof, and Cutting Tool

A method of manufacturing a surface coated member comprising a substrate and a coating layer to be formed on a surface of the substrate, the method comprising the steps of:

• forming on the surface of the substrate, as a layer constituting the coating layer, an under layer comprising at least one compound containing at least one element selected from the group consisting of metals in Groups 4, 5 and 6 of the periodic table, aluminum and silicon, and oxygen;
• forming, as a surface layer of the coating layer, an outermost layer composed of at least one compound selected from carbide, nitride and carbon nitride of at least one element selected from the group consisting of metals in Groups 4, 5 and 6 of the periodic table, aluminum and silicon;
• and
• polishing the outermost layer until a plurality of first phases constituting the under layer are exposed within a second phase constituting the outermost layer in the surface of the coating layer.
