PROBLEM TO BE SOLVED: To provide a lubricant including polymer filling cylindrical roller bearing of a low torque, by preventing the projection of a lubricant including polymer from the side end surfaces of an inner ring and an outer ring, owing to a temperature rise. SOLUTION: In this lubricant including polymer filling cylindrical roller bearing, a lubricant including polymer 5 is filled in an inner ring 2, an outer ring 3, a cylindrical roller, and in a space formed of the rings and the roller. The side end surfaces 7 of the lubricant including polymers 5 are arranged at the inner sides from side end surfaces 8 and 9 of the inner ring 2 and the outer ring 3, by providing the intervals larger than the curvature radius (r) of the circular arc form angle parts 10 and 11 formed on the outer peripheral surface of the inner ring 2 and on the inner peripheral surface of the outer ring 3.
