Some of crystal grains composing the complex nitrdie or complex carbonitride layer have a cubic structure. In crytal grains having the cubic structure, the average crystal grain misorientaion is 1 degree or more; or 2 degress or more, based on analysis of the polished surface as a surface in the perpendicular direction to a surface of the layer. A peak exists in a range of 1-2 degrees of the average crystal grain misorientation in the frequency distribution of the average crystal grain misorientation and the area ratio.
