摘要：There is provided a sliding part in which a surface coverage ratio of copper inthe sliding part increases. A bearing which is the sliding part is formed by filling the rawpowder into the filling portion of the forming mold, compacting the raw powder to form
a powder compact and sintering the powder compact A copper-based raw powder iscomposed of a copper-based flat raw powder having an average diameter smaller thanthat of an iron-based raw powder and an aspect ratio larger than that of the iron-basedraw powder and a copper-based small-sized raw powder having the average diameter issmaller than that of the copper-based flat raw powder The copper is allowed to
segregate at the surface of the sliding part. In the bearing in which the copper-based flatpowder segregates at the surface, the surface is covered with the copper-based small-sized raw powder that has emerged on the surface, as well as the copper-based flat rawpowder thereby it is possible to increase the surface coverage ratio of copper.
