A dam forming method and a method for manufacturing a laminate capable of suppressing the occurrence of a height difference in the thickness of a dam. A dam forming method is used in a method for manufacturing a laminate in which a first base member and a second base member are laminated via a fill material, including: forming a dam surrounding an application region for the fill material on the first base member; and applying the fill material to the application region. The dam forming method includes: applying a dam-forming resin composition on peripheral edges of the first base member by accelerating the application speed of the dam-forming resin composition continuously or stepwise from the start to the end of the application; and curing the applied dam-forming resin composition.

Dam forming method and method for manufacturing laminate

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.
