Abstract:
A surface-coated tool includes a substrate and a coating film formed on the substrate. The coating film includes an alternate layer in which one or more A layers and one or more B layers are alternately stacked. The A layer and the B layer each have a thickness not smaller than 2 nm and not greater than 100 nm. An average composition of the A layer is expressed as TiaAlbSicN (0.5
