A pair of sliding parts in which a plurality of dimples is arranged on at least one of sealing faces that relatively slide on each other is characterized in that each of the plurality of dimples is provided independently from the other dimples, and arranged in such a manner that the plurality of dimples having different opening diameters is randomly distributed.
