The lubricant oil includes at least one of sulfur (S) and phosphorus (P) and at least one of zinc (Zn), calcium (Ca), magnesium (Mg), sodium (Na), barium (Ba) and copper (Cu). The amorphous hard carbon film comprises carbon (C) as a major component, and hydrogen (H) in the range from 5 to 25 atomic % and a predetermined amount of boron (B), aluminum (Al), manganese (Mn) or molybdenum (Mo) assuming that the total atomic % of the amorphous carbon film is 100.
