An optical device producing method includes: Step A of forming a wall portion surrounding an application region for a photocurable resin composition on an optical member or a transparent panel; Step B of applying a photocurable resin composition to the application region; Step C of forming a laminate by laminating the optical member and the transparent panel via the photocurable resin composition under a reduced-pressure atmosphere lower than atmospheric pressure; and Step D of removing babbles in the photocurable resin composition by pressurizing the laminate. In Step B, at least the height of the photocurable resin composition on the side of the wall portion is made higher than the height of the wall portion, and the photocurable resin composition is applied so that the laminate formed in Step C has a plurality of separated spaces separated by bubbles formed in the thickness direction of the photocurable resin composition.

A process capable of commercial scale manufacturing of inexpensive, multilayered shaped film product, without the waste of die-cutting and which products are capable of use independent of a supporting structure on which they are formed, includes placing a first mask over a substrate; delivering a first film-forming composition through the first mask to form a first raw shape on the substrate; removing the first mask; placing a second mask over the first raw shape; delivering a second film-forming composition through the second mask to form a second raw shape on the first raw shape; removing the second mask; and solidifying the first and second raw shapes to provide the shaped film product disposed on the substrate.

A method of producing a conversion element includes providing a substrate having a surface; forming a first mask structure above the surface, wherein the first mask structure has first webs and first openings arranged between the first webs and the first openings form cavities in which the surface of the substrate is accessible; arranging a second mask structure above the first mask structure, wherein the second mask structure has second webs and second openings arranged between the second webs, the first webs are at least partly covered by the second webs, and the cavities remain at least partly accessible through the second openings; spraying a material into the cavities through the second openings; removing the second mask structure; and removing the first mask structure.

Provided is a method of manufacturing an electrostrictive element by which an electrostrictive element including an expandable and contradictable film electrode having a thin and uniform thickness can be easily formed. In a method of manufacturing an electrostrictive element 1, screen printing is performed while a first jig 12 contacts with a face of a dielectric film 2 opposite to a face where screen printing is performed such that the first jig 12 surrounds an area where the screen printing is performed. Thus, a film electrode 3 is formed.
