PROBLEM TO BE SOLVED: To provide a more inexpensive optical element fixing component while securing the adhesive strength of an optical element and easiness in assembly work, and an optical isolator using the same. SOLUTION: The invention is the plate type optical element fixing component for fixing a rectangular optical element 6, wherein a circular recessed part 2 having a diameter smaller than the length of the diagonal of the rectangle is formed, and an aperture part 3 through which light is transmitted is formed in the center part of the circular recessed part 2, then four clearance parts 4 on which the corner parts 7 of the rectangle abut in installing the rectangular optical element 6 are provided on the circumference of the circular recessed part 2. The optical isolator is equipped with a polarizer and a Faraday rotator fixed by the optical element fixing component. COPYRIGHT: (C)2006,JPO&NCIPI
