A sliding material which is used for bearings, washers and other parts of automobiles, industrial machines, agricultural machines and the like, possesses an excellent abrasion resistance, and is useful under sever boundary lubricating conditions. The sliding material comprises a back plate (5) of a steel plate and a sinter bearing layer integrally provided on one surface of the back plate (5). A powder (2) of a hard material is dispersed in an amount of 0.5 to 20% by weight in a matrix (4) of the sinter bearing layer. The matrix (4) comprises 1 to 30% by weight of Pb and 1 to 15% by weight of Sn with the balance consisting of Cu. The powder (2) of a hard material comprises 7.5 to 9.5% by weight of Cr, 27 to 30% by weight of Mo, and 2.0 to 3.0% by weight of Si with the balance consisting of Co.
