To provide a cage for a needle bearing, and a needle bearing with improved reliability.

Since deformation of a whole cage 12 is suppressed by separating cut faces of cut parts 12e even if excessive centrifugal force along with rotation and revolution of the needle bearing 10 is generated, the stresses of the cage 12 can be released to prevent breakage or the like. Further, it is the secondary effect that a lubricating oil can be supplied from an inside diameter to an outer diameter through the cut parts 12e to improve lubricity.
