PROBLEM TO BE SOLVED: To solve the problem that the surface of a diamond film deposited by vapor phase synthesis is extremely rough and becomes increasingly hostile to mating materials as well as in friction coefficient, although diamond is minimal in friction coefficient if it is smooth, and to attain sliding characteristics of decreased friction coefficient and decreased attacks on mating materials when a diamond coated surface is rough. SOLUTION: The member is a sliding member coated with film, in which an upper-layer film composed of a carbon film, a metal film, or a compound film of 20 to 2,000 Knoop hardness is laminated on a lower-layer film which is composed of a diamond film or a film containing >=30 vol.% diamond microcrystals and has >8,000 Vickers hardness or Knoop hardness.
