PROBLEM TO BE SOLVED: To provide a lubricant-containing polymer-packed roller bearing wherein a lubricant-containing polymer and a rolling body are prevented from contacting with each other to keep smooth rotation over a long period of time and a method for manufacturing the bearing. SOLUTION: The roller bearing 1 has a space established with an outer ring 2, an inner ring 3 and a rolling body 4, and a lubricant-containing polymer 6 packed in the space. The lubricant-containing polymer 6 is made of a hydrocarbon resin and a hydrocarbon lubricant contained in the resin, and a film 5 made of at least one of a perfluoroalkylcarboxylic acid and a perfluoroalkylpolyether carboxylic acid is formed, at least, on an inner peripheral surface of the outer ring 2, an outer peripheral surface of the inner ring 3 and the surface of the rolling body 4 of the roller bearing 1. |
