SOLUTION: This coated cutting tool has a coating film of a plurality of layers on a base material. The coating film has respectively one or more layers of a first film composed of one kind of compound selected from nitride of TiSi, carbide, carbonitride, oxynitride and carboxynitride, and a second film composed of one kind of compound selected from nitride, carbide, carbonitride, oxynitride and carboxynitride of one kind of metal M selected from Zr, Hf and ZrHf. The first film and the second film are alternately laminated. COPYRIGHT: (C)2004,JPO
