A rolling bearing 10 includes an outer ring fixed to a housing, an inner ring that is arranged so as to face the outer ring in the radial direction of the rolling bearing and that is fixed to a rotating shaft, balls that are rollably arranged at positions between the outer ring and the inner ring in the radial direction, and seal members that seal up an annular space between the outer ring and the inner ring. Escape passages through which fluid is circulated in the axial direction of the rolling bearing so as to be allowed to escape are formed in a contact portion of the outer ring, which contacts the housing.
