Provided are a rolling bearing and a holder, the rolling bearing having a sliding surface with excellent slidability even under conditions of high slip velocity and high surface pressure lubricating oil. The holder holds the rolling element of the rolling bearing used in a lubricating oil environment, and the holder has a base material and a sliding layer formed on the surface of the base material. The sliding layer is a fluororesin layer in which either: (1) the fluororesin has a three-dimensional structure in the sliding layer surface where the fluororesin layer does not make contact with the base material and in layers proximal thereto, the fluororesin has a two-dimensional structure in the surface where the fluororesin layer makes contact with the base material and in layers proximal thereto, and the content ratio of the three-dimensional structure of the fluororesin continuously decreases from the sliding layer surface toward the surface in contact with the base material; or (2) the three-dimensional structure of the fluororesin is continuous from the sliding layer surface toward the surface in contact with the base material. |
