The thickness of the rotator 2 is set so that the plane of polarization of an incident light beam may be rotated by 45 deg. in the case of impressing saturation magnetic field in the direction of the optical axis L of the incident light beam. Two polarizers 3 and 3' are constituted of an absorption type polarizer or a double refraction polarizer. Resin such as thermosetting type resin or ultraviolet-curing resin, soldering or low melting point glass is considered as a member used for the substrates 5 and 5', and it is stuck to fix the optical element.
