Abstract
A method of producing a structure by three-dimensionally processing a flat member includes a preparing, a first forming and a second forming. In the preparing, a substrate is prepared. In the first forming, an etching mask is formed on the substrate. The etching mask has at least two openings, and areas of the two openings are different from each other. In the second forming, at least a part of a three-dimension surface shape of the structure is formed on a surface of the substrate by a dry-etching on the substrate in accordance with the area of the opening of the etching mask.
