Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a diamond film-coated member in which a diamond film is applied on an iron-based alloy with excellent adhesion; and to provide a method for producing the same. SOLUTION: An intermediate layer 10 comprising tungsten is applied on a base material 1, and the diamond film is applied on the intermediate layer 10. The intermediate layer 10 has fine areas 4 divided by grooves 3, and the longest distance 8 on the surface of each fine area 4 is set to be >100 to
