PROBLEM TO BE SOLVED: To provide a cutting insert with a titanium oxycarbonitride coating and a method for manufacturing the same.SOLUTION: The method for manufacturing a coated cutting insert and the coated cutting insert includes steps of: providing a substrate which has a surface; and depositing a CVD coating layer of titanium oxycarbonitride. A gaseous mixture from which the coating layer of titanium oxycarbonitride is deposited, has a composition of nitrogen, methane, hydrogen chloride, titanium tetrachloride, acetonitrile, carbon monoxide, and hydrogen. The coating layer of titanium oxycarbonitride includes titanium oxycarbonitride whiskers having, as measured in a two-dimensional plane view, an average length longer than about 1.0 μm, an average width larger than about 0.2 μm, and an average aspect ratio larger than about 2.0.
