Coated tool

A coated tool, comprising:

• a substrate and a coating layer disposed on a surface of the substrate, the coating layer including a first stack structure and a second stack structure,
• the first stack structure having a structure in which two or more kinds of layers with different compositions are periodically stacked, wherein the average layer thickness of each of the layers is 60 nm to 500 nm,
• the second stack structure having a structure in which two or more kinds of layers with different compositions are periodically stacked, wherein the average layer thickness of each of the layers is 2 nm to less than 60 nm,
• the layers constituting the first stack structure and the layers constituting the second stack structure including at least one selected from the compounds including at least one metal element selected from Ti, Nb, Ta, Cr, W, Al, Si, Sr and Y and at least one non-metal element selected from carbon and nitrogen,
• wherein the first stack structure is an alternate stack structure including two kinds of layers with different compositions stacked alternately each in two or more layers, and
• wherein the coating layer includes a structure including the first stack structures and the second stack structures stacked alternately and continuously each in two or more structures.
