PROBLEM TO BE SOLVED: To provide a coated cutting tool that can demonstrate the improvement in wear resistance in one or more cutting applications.SOLUTION: The coated cutting tool includes a substrate and a coating bonded to the substrate. The coating includes: an inner layer deposited by physical vapor deposition and containing aluminum, one or more kinds of metallic elements selected from a group consisting of groups IVB, VB and VIB metallic elements in the periodic table, and one or more kinds of non-metallic elements selected from a group consisting of groups IIIA, IVA and VIA non-metallic elements in the periodic table; and an outer layer deposited by physical vapor deposition on the inner layer.
