    摘要: Provided is a method of manufacturing an optical element having a structure, which is represented by a one-dimensional lattice, with high yield with the use of a sol-gel material. A titanium based sol-gel material is applied onto a substrate (1), and then is subjected to vacuum drying to form a titania sol layer (2) corresponding to a dried sol-gel film. Onto the titania sol layer (2), a line-and-space structure is transferred by embossing using a mold (3), and then the mold (3) is separated. Thus, a titania sol layer (4) having the structure is formed. Next, heating is performed to accelerate the dehydration condensation reaction of the sol-gel material to cure the sol-gel material, and thus a titanium oxide structure portion (5) having the line-and-space structure is formed.
