Abstract
A surface-coated cutting tool of the present invention includes a substrate and a coated layer formed on the substrate, and the coated layer is a physical-vapor-deposition layer having a thickness of 10 μm or more. A surface region having a thickness of 1 μm from a surface of the coated layer includes a first region whose integrated residual stress is a compressive stress and a second region whose integrated residual stress is a tensile stress, and the integrated residual stress of the surface region falls within the range of −1.5 to 1.5 GPa in any region included in the surface region.
