METHOD FOR MANUFACTURING MOLD, MOLDED BODY HAVING FINE PROTRUSIONS AND RECESSESES ON SURFACE, AND METHOD FOR MANUFACTURING SAME

摘要

A method for manufacturing a mold (18) in which an oxide film (14) that has a plurality of fine holes (12) is formed on the surface of an aluminum base material (10), the method including: (a) a step in which voltage is applied to the machine-processed aluminum base material, and the surface of the aluminum base material is anodized to form the oxide film; and (b) a step in which at least part of the oxide film that is formed in step (a) is removed. In step (a), the voltage (Va[V]) just before the completion of step (a), and the time (ta[s]) from the start of voltage application until the voltage (Va[V]) is reached satisfy general formula (i) 0.010
