Abstract
A surface-coated cutting tool includes a base material and a coating formed on the base material. The coating includes an α-AlOlayer. The α-AlOlayer contains α-AlOcrystal grains and sulfur, and has a TC(006) of more than 5 in texture coefficient TC(hkl). The sulfur has a concentration distribution in which a concentration of the sulfur decreases in a direction away from a base-material-side surface of the α-AlOlayer, in a thickness direction of the α-AlOlayer.
