PROBLEM TO BE SOLVED: To provide a cylindrical roller bearing for reducing the number of steps of pushing two cylindrical rollers into a pocket in the case where those cylindrical rollers are confined in an axially arranged state into one pocket of an integral type cage.SOLUTION: A cage 5 comprises: a first drop stopping part 14 for stopping the dropout of a first cylindrical roller 3 confined in a pocket 10; and a second drop stopping part 15 for stopping the dropout of a second cylindrical roller 4 confined in the pocket 10. The axial interval Wa between the first drop stopping part 14 and the second drop stopping part 15 is larger than the roller length Lw of the first cylindrical roller 3 or the second cylindrical roller 4.
