A slide member is provided with a metal back, a bearing alloy layer disposed over a first surface of the metal back, and a diamond-like carbon layer disposed at least over a second surface of the metal back, the second surface being located on an opposite side of the first surface. The diamond-like carbon layer has a hardness equal to or less than 1000 HV and when subjected to infrared spectroscopy analysis, exhibits absorption wavenumbers of following wavenumbers (1) to (5) originating from different chemical bonding states: wavenumber (1): 2800-3100 cm −1 , wavenumber (2): 1500-1800 cm −1 , wavenumber (3): 1200-1500 cm −1 , wavenumber (4): 3300-3600 cm −1 , wavenumber (5): 730-930 cm −1 . n The relation (P 1 +P 3 )/(P 1 +P 2 +P 3 )≧0.50 is satisfied when an integrated value of absorption rate with respect to wavenumbers (1), (2), and (3) is represented as peak area values P 1 , P 2 , and P 3 , respectively. |
