[Task] The solid-lubricant layer applied on the surface of Al or Cu-based bearing alloy is improved so as to satisfactorily demonstrate the properties of the solid lubricant. [Means for Solution] The solid lubricant dispersed in the solid-lubricant solid-lubricant layer exhibits 85% or more of the relative C axis intensity ratio defined below. The relative C axis intensity ratio = the accumulative intensity of (002), (004) and (008) planes relative to the accumulative intensity of (002), (004), (100), (101), (102), (103), (105), (110) and (008) planes detected by X ray diffraction. |
