Abstract

The hard coating layer includes at least a complex nitride or complex carbonitride layer expressed by the composition formula (TiAl)(CN). The average Al content ratio xthe average C content ratio ysatisfy 0.60≤x≤0.95 and 0≤y≤0.005, respectively, each of the xand yis in atomic ratio. The crystal grains constituting the complex nitride or complex carbonitride layer include a crystal grain having the cubic structure. Predetermined average crystal grain misorientation and inclined angle distribution exist in the crystal grains having the cubic structure.
