Abstract
A surface-coated cutting tool of the present invention includes a base material and a coating film formed on the base material. The coating film includes at least one TiBlayer. The TiBlayer includes Cl together with TiB. This surface-coated cutting tool is characterized in that assuming that in the TiBlayer, a first region represents a region having a thickness of 0.5 μm from an interface on the base material side, and a second region represents a region having a thickness of 0.5 μm from an interface on the coating film surface side, an atomic ratio Cl/(Ti+Cl) between Ti and Cl is higher in the second region than in the first region.
