PROBLEM TO BE SOLVED: To achieve very easy quantity governing and filling into a desired portion, to avoid adhesion to an unnecessary portion unlike a powdery or pasty bonding agent, to ensure easy handling, to achieve simple production and improvement of dimensional accuracy in the case of a spherical type, and to comply with miniaturization of the whole components. SOLUTION: In an optical element obtained by fixing a polarizer, a Faraday rotator and permanent magnets arranged around the Faraday rotator to a holder, the bottom of the holder has a round-bottomed groove formed along outer edges of the polarizer, Faraday rotator and permanent magnets, and by filling spherical low melting glass or solder into the round-bottomed groove, the holder, polarizer, Faraday rotator and permanent magnets are fixed.
