摘要： The present invention relates to a sliding member having a novel micropore structure and an improved seizure resistance and seal property. Conventionally, the surface roughness of a sliding member is defined by, for example, maximum and/or average roughness. In the present invention, first, there is prepared a sliding member which has a hardness of at least HRc 50 and has micropores for determining the surface roughness of the sliding surface thereof, wherein the micropores, when measured with a particle counter, are present essentially in an amount ranging from 5% to 40% based on an area of the sliding surface and ranging from 2,000 to 150,000 per mm.sup.2 on the sliding surface and have a diameter of at least 0.5 .mu.m. A top portion of ridges which define the micropores is slightly rounded, thereby providing flat or round configuration in terms of the relative load curve, the relative load curve being defined by the accumulative percentage (t.sub.k) and the cutting depth (CV.sub.k) and the accumulative percentage (t.sub.k) being both: an accumulative percentage (t.sub.k) of 5% or less at a cutting depth (CV.sub.k) of less than 1 .mu.m and an accumulative percentage (t.sub.k) of more than 5% but less than 40% at a cutting depth of less than 0.5 .mu.m.
