The magnetic fluid seal includes: an annular seal body fixed to one raceway; a magnet ring that forms a magnetic field between the seal body and an annular step provided on the other raceway; a magnetic fluid held in a magnetic field, and a seal lip that lightly contacts the side surface of the annular step is provided on the free end edge of the seal body in an axially inner portion of the magnetic field. Sealed rolling bearing.
