The present invention relates to a sliding member comprising a backing metal layer and a sliding layer composed of a copper alloy providing a firm engagement of the sliding layer with the backing metal layer. The lining metal layer includes hypoeutectoid steel containing 0.07 to 0.35 mass % of carbon, and has a structure including a ferrite phase and pearlite. The backing metal layer has a high ferrite phase part on the joint surface with the sliding layer, the volume ratio Pc of pearlite in the structure of the central part in the thickness direction of the backing metal layer and the volume ratio of pearlite in the high ferrite phase part The relationship of Ps is: Ps/Pc≤0.4. |
