PROBLEM TO BE SOLVED: To provide a roller with a cage which has successfully been resinified with improved lubricity while securing cage strength. SOLUTION: In this roller 1 with a cage having a cage 2 of a resin compact, a plurality of post parts 4 partitioning respective pocket parts 6 in a cage circumference direction, and a pair of annular parts 3 each connecting both axial ends of the post parts 4 to each other are formed in the cage 2; and, in the annular parts 3, oil supply passages 10 opened to axial end surfaces of the annular parts 3 and communicating with the pocket parts 6 are each formed in a form cut out in the cage radial direction of the annular part 3 on at least either the inner peripheral surface or the outer peripheral surface in the cage radial direction.
