PROBLEM TO BE SOLVED: To provide a coated member capable of reducing the residual compressive stress in a boron nitride coating film, and enhancing the wear resistance of the coated member under a service environment requesting the wear resistance. SOLUTION: In the coated member, a compound coating film consisting of boron, nitrogen and oxygen is coated on a surface of a base material. The compound coating film has a tissue structure with amorphous boron nitride being dispersed in crystalline boron nitride. The sectional area of a zone of the amorphous boron nitride in the section of the compound coating film is replaced by the area of a circle, and the diameter of the circle is obtained as the diameter of the equivalent circle. In this case, the diameter is below 10 nm. COPYRIGHT: (C)2007,JPO&INPIT
