STAMPER, METHOD FOR PRODUCING SAME, AND METHOD FOR PRODUCING MOLDED BODY

摘要

A method of manufacturing a stamper of the invention includes: performing a blast process on an aluminum base material, and thereafter anodizing a processing surface of the blast-processed aluminum base material so that a structure which includes a rough rugged structure having an specific arithmetic average roughness Ra and a specific period Sm and a fine rugged structure which is formed on the rough rugged structure to have a shorter period than that of the rough rugged structure is formed on a surface of the aluminum base material. In the stamper of the invention, by anodizing the processing surface of the blast-processed aluminum base material, the structure which includes the specific rough rugged structure and the fine rugged structure which is formed on the specific rough rugged structure to have a shorter period than that of the rough rugged structure is formed on the surface of the aluminum base material.
