A thrust roller bearing cage (11) is a cage (11) provided to a thrust roller bearing and having a plurality of pockets (21) that house needle rollers (13). The cage (11) includes projections (44) that are formed by bending a radially outer area of the cage (11) inwardly along the radius and that project inwardly along the radius toward a radially outer area of the pockets (21) to make contact with end faces (16) of the rollers (13). The projections (44) have corners (45) that make contact with the end faces (16) of the rollers (13). The corners (45) are press-flattened.
