Provided is a cutting tool having high weld resistance and wear resistance. The cutting tool (8) comprises a base (1) including a hard alloy and a coating layer (7) located on a surface of the base (1), wherein the coating layer (7) comprises at least one TiCN layer (2), an Al 2 O 3 layer (4) and an outermost layer (6) which are laminated in order from a side of the base (1), and a content of Cl at a thickness-center position of the TiCN layer (2) is higher than a content of Cl at a thickness-center position of the outermost layer (6) and the content of Cl at the thickness-center position of the outermost layer (6) is higher than a content of Cl at a thickness-center position of the Al 2 O 3 layer (4) in a glow-discharge emission spectrometry (GDS analysis). |
