STAMPER ALUMINUM DIE AND METHOD FOR MANUFACTURING THE SAME, ALUMINUM DIE MATERIAL, STAMPER AND METHOD FOR MANUFACTURING THE SAME, AND METHOD FOR MANUFACTURING TRANSFER OBJECT

摘要

PROBLEM TO BE SOLVED: To provide a stamper aluminum die capable of preventing a crystal grain pattern from being generated and a method for manufacturing the same; an aluminum die material; a stamper and a method for manufacturing the same; and a method for manufacturing a transfer object.SOLUTION: The stamper aluminum die has 50 μm or less of a mass size of crystal grains existing on the surface in the other areas excluding an area having the highest area rate from areas where an orientation difference from a {001} plane is defined as 0-30 degrees, 30-40 degrees or 40 degrees or more. The aluminum die includes Mg of 0.1-3.0 wt.% desirably, and Fe of 200 ppm and Si of 100 ppm or less as inevitable impurities. The total amount of inevitable impurities (where, Fe and Si are also included) is 500 ppm or less.
