摘要

PROBLEM TO BE SOLVED: To provide a mold having a nonreflective dust-proof structure which forms a minute needle structure accurately and efficiently by a reduced number of processes even when the mold has a molding surface of a small radius of carvature. SOLUTION: An amorphous layer 4 is formed on the molding surface which is processed in the final shape of a mold base material 1, and an electrolytic plated layer 5 having a minute needle structure is formed on the amorphous layer.
