PROBLEM TO BE SOLVED: To provide a rolling bearing realizing torque reduction by suppressing spin slip and reducing rolling resistance of a rolling body and a raceway groove, and capable of receiving a radial load, an axial load in both directions, and a moment load. SOLUTION: A plurality of rolling bodies 5 wherein an outer diameter 5a forming a rolling contact face also has a curvature in an axial direction and a radius is smaller than a radius of a raceway surface, are incorporated in a raceway groove 3 between outer and inner rings 1 and 2. Adjacent rolling bodies 5 are each arranged so as to mutually cross, and the outer diameter 5a of each rolling body 5 constantly contact two points at raceway surfaces 1a or 1b of one race 1 and raceway surfaces 2b or 2a of another race 2.
