Abstract
A coated tool according to the present disclosure includes a base body made of WC-based cemented carbide containing WC particles as a hard phase component and Co as a main component of a binding phase, a coating layer located on the base body, and an intermediate layer located between the base body and the coating layer. The intermediate layer contains Ti, and has an average layer thickness of 1 nm or more and 15 nm or less. The coating layer includes a first coating layer in contact with the intermediate layer. The first coating layer includes at least one element selected from the group consisting of Al, Group 5 elements, Group 6 elements, and Group 4 elements except for Ti, at least one element selected from the group consisting of C and N, Si, and Cr.
