PURPOSE:To form a mold for mass-producing a precise dimension product such as a multi-core fiber connector ferrule or grating by molding with high accuracy. CONSTITUTION:In the manufacture of a mold, sputtering 2 and electroforming 3 are performed on the basis of a three-dimensional shape 1 obtained by the anisotropic etching of a single crystal such as silicone or quartz and the shape 1 is transferred to form the mold with high dimensional accuracy of submicron. |
