  "abstract": "A holding jig and a related technique thereof, which is a holding jig for holding an optical element, including: a base; a plurality of holding mechanisms that hold a peripheral edge of the optical element; a biasing member that biases a first holding mechanism among the plurality of holding mechanisms so that the first holding mechanism rotates toward a side surface of the optical element to be held; and a lever that can be rotated in a direction parallel to a plane including a rotation direction of the first holding mechanism, wherein the lever is rotated to fix the first holding mechanism, thereby reducing a biasing force added on the optical element by the biasing member.",
