Claim 2:
3. The sliding machine according to claim 2, wherein an organic film is present on the metal surface, wherein when positive ion spectrum analysis is performed with time-of-flight secondary ion mass spectrometry (TOF-SIMS), the organic film satisfies conditions below with reference to a reference area that is a peak area (S0) around m/z 29.04 (C2H5+):
a peak area (S1) around m/z 30.03 (CH4N+) is 1.5 times or more the reference area (S1/S0≥1.5);
a peak area (S2) around m/z 70.07 (C4H8N+) is 0.3 times or more the reference area (S2/S0≥0.3); and
a peak area (S3) around m/z 84.08 (C5H10N+) is 0.1 times or more the reference area (S3/S0≥0.1).
