The invention is related to a bearing material having multiple layers therein and a method for manufacturing the same. The invention features that a bearing layer consisting mainly of an integrated resin powder is formed on a porous layer covering a back metal, such as a steel plate of like, that the integrated resin powder consists of P T F E resin precipitate and F E P resin precipitate and/or P F A resin precipitate and that each particle of the integrated resin powder is covered with Pb-Sn alloy powders. Accordingly, the integrated resin powder independently provides a predetermined lubricating property. In addition, since these resin precipitates are in unity, it is possible to maintain excellent cavitation resistance property and load resistance property, even under severe boundary conditions. Furthermore, since each of the integrated resin powder is covered with the Pb-Sn alloy powder, an uniform and deep penetration of the alloy powder into pores of the porous layer can be easily obtained.
