| 摘要 |
A optical element forming die has a die base body; and an optical surface transferring layer to form an optical surface of the optical element, the optical surface transferring layer formed by depositing an amorphous alloy having a supercooled liquid region on the die base body, wherein a plurality of projections or concavities are provided on the optical surface transferring layer so that a plurality of concavities or projections corresponding to the plurality of projections or concavities on the optical surface transferring layer are transferred and formed on the optical surface of the optical element.
