摘要： A cutting tool includes a substrate and a coated film arranged on the substrate. The coated film includes a first layer. The first layer includes a plurality of crystal grains. The crystal grains are composed of AlxTi1-xCyN1-y, wherein x is more than 0.65 and less than 0.95, and y is not less than 0 and less than 0.1. In a first region, the crystal grains have an average aspect ratio of not more than 3.0. In a second region, the crystal grains have an average aspect ratio of more than 3.0 and not more than 10.0. The crystal grains include crystal grains having a cubic crystal structure. The first layer has a ratio of an area occupied by the crystal grains having a cubic crystal structure of not less than 90%. The first layer has a thickness of not less than 2 μm and not more than 20 μm.
