光アイソレータ。 A pair of polarizing elements and a Faraday rotator disposed between them, or a holder to which the Faraday rotator is fixed, are fixed to the inner wall of a hollow cylindrical permanent magnet that applies a magnetic field to the Faraday rotator, and a case is attached to the hollow cylinder. In the optical isolator, the hollow cylindrical permanent magnet is attached to a first hollow cylindrical permanent magnet and a second hollow cylindrical permanent magnet having mutually different inner diameters, which are fixed in the axial direction. An optical isolator characterized in that a holder or a Faraday rotator is fixed to a stepped portion formed on the inner wall.
