The present invention provides an optical element fixing structure, an optical element fixing body, an optical element and an optical element holder which make tightening with a fixing screw unnecessary, prevents thereby a decrease in performance, such as the generation of strain in the optical element such as a crystal, and can improve the mounting accuracy. The optical element fixing structure 10 includes an optical element 6 and an optical element holder 1 to fix and mount the optical element 6. The optical element 6 has one or multiple slits 8 as strain and stress absorbing means in the thickness direction in the end part thereof, and the optical element holder 1 has depressing means 3 to fix the optical element 6 by depressing at least one of the front surface and the back surface of the optical element 6 outside the slit 8.
An optical element fixing structure, characterized in that the optical element fixing structure is an optical element fixing structure to fix an optical element such as a crystal which comprises an optical element and an optical element holder to fix and mount the optical element, in that the optical element has one or multiple slits in the thickness direction in an outer edge part thereof (which is present on the optical element but outside a working surface of the optical element and can be used as a portion to fix the optical element to the optical element holder;
