Abstract
Disclosed is a bearing having an improved corrosion resistance, which comprises: a base metal; and, a bearing layer of Cu-series alloy having a skeleton structure of Cu alloy. The clearance of the skeleton structure are filled essentially with Pb-containing phase. The deterioration of corrosion resistance due to dissolution of Pb in the clearances into degraded engine oil is prevented by including into the Pb-containing phase In at a depth exceeding approximately 20 .mu.m mearued from the surface of the bearing layer.
