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 the other raceway; and a magnetic fluid held in the magnetic field. A sealing member made of a non-magnetic material is provided on the axially outer side of the sealing portion in which the magnetic fluid is retained, and an axially outer end opening of the labyrinth seal portion formed by the sealing member and the magnetic fluid A sealed bearing characterized in that the radial position of the seal portion of the seal is different from the axial outer end.
