A die (10) has an anodic oxidation porous alumina layer on the surface, and has a plurality of first depressed sections (12) and a plurality of second depressed sections (14), wherein the plurality of second depressed sections (14) have two-dimensional size of 190 nm - 50 µm inclusive when viewed from the normal direction of the surface, and have a shape in which a plurality of fine depressed sections (15) having two-dimensional size of 10 nm - 200 nm inclusive are formed on the inner surface, wherein the plurality of first depressed sections (12) have two-dimensional size of 10 nm - 200 nm inclusive, and are formed between the plurality of second depressed sections (14), and wherein the average value of the two-dimensional size of the plurality of second depressed sections (14) is greater than the average value of the two-dimensional size of the plurality of first depressed sections (12). Provided are a Moth-eye die, the wettability to hardening resin of which has been improved, and a method for manufacturing same. |
