Abstract: A slide member provided with a substrate; and a slide layer provided in a surface side of the substrate is disclosed. The slide layer includes a soft layer in the surface side and a DLC layer in the under surface side of the soft layer. The soft layer has a Young's modulus E ranging from 6 to 30 GPa, hardness Ht ranging from 0.2 to 3.0 GPa, and a value of ratio [E/Ht] of the foregoing ranging from 10 to 30. The DLC layer has a hardness Hd ranging from 5 to 60 GPa.

Abstract: 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.The relation (P1+P3)/(P1+P2+P3)≧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 P1, P2, and P3, respectively.
