A plain bearing comprises a metal cylinder as an external member and a resinous cylinder as an internal member, in which the outer surface of the resinous cylinder is firmly engaged and bitten with a concavo-convex portion formed on the inner surface of the metal cylinder. A process for manufacturing the plain bearing comprises producing the metal cylinder, forming the concavo-convex portion on the inner surface of the metal cylinder, combining the concavo-convex portion of the metal cylinder with the resinous cylinder, inserting a core pin into the interior of a combined cylinder of the metal cylinder and the resinous cylinder, squeezing the combined cylinder through a draw die and producing a finished plain bearing.
