PROBLEM TO BE SOLVED: To provide a manufacturing method for reducing cost by easily forming a roller stopper, by securing strength without using a thick plate, in a cage for a thin thrust roller bearing having a thin roller diameter. SOLUTION: This cage 10 for the thrust roller bearing is manufactured by a cage member forming process of forming a cage member 40 having a thickness corresponding to a width in the axial direction of the cage 10 by bending and superposing a thin plate thinner than a width in the axial direction of the finished cage 10, a pocket forming process of punching a pocket 20 for housing a roller 30 in the cage member 40, and a roller stopper forming process of forming the roller stopper 24 on a wall surface 22 of the pocket 20 by pushing out a column part 12 of the cage member 40 pressed to a projection part of a metal mold to an opening part of the pocket 20 by pressing the metal mold having a continuous projection part on the circumference from above and below the cage member 40.
