A sliding member is provided which has a sliding surface with excellent sliding properties even under conditions of high surface pressure, high sliding speed and being in lubricant; a roller bearing and a retainer are also provided. This sliding member is used in a lubricated environment and has a sliding layer which is formed on an iron-base metal substrate. The sliding layer comprises an underlayer which is disposed on the iron-base metal substrate and which contains a heat resistant resin and a first fluororesin, and a second fluororesin layer disposed on the underlayer surface. The heat resistant resin is a resin which, in the main chain of the polymer structure, contains carbon atoms and at least one of oxygen atoms, nitrogen atoms and sulfur atoms, and the second fluororesin layer is a cross-linked fluororesin layer which is cross-linked at least near the surface layer. |
