A rolling-sliding member that is high in hardness and continues to have a passivation film reliably even after being subjected to a process that does not require any processing for removal of scale etc., as well as a rolling bearing using the same and a method for manufacturing the rolling-sliding member.

A thrust roller bearing including: a pair of races each of which has an annular plate; a cage interposed between the pair of races, formed by a single annular plate including a bent portion bent in an intermediate region in a radial direction of the cage such that a plurality of projecting portions to project in a thickness direction of the cage are formed on a first side and a second side of the cage, and a plurality of pockets stamped out in the thickness direction at predetermined intervals in a circumferential direction of the cage; and a plurality of rollers received respectively in the pockets. At least two projecting portions are formed on each of the first side and the second side of the cage; and a plurality of race-contacting projection portions are arranged on a surface of at least one of the two projecting portions on at least one of the first side and the second side of the cage at predetermined intervals in the circumferential direction of the cage.
