A molding device produces a porous film from a molding material which is an emulsion. In a case where a volume of a dispersed phase is X 1 and a volume of a continuous phase is X 2, the molding material has a value of X 1 /(X 1 +X 2 ) within a range of 0.5 or more and 0.9 or less. In the molding material, a specific gravity of the dispersed phase is greater than a specific gravity of the continuous phase. The molding material includes a water phase containing a curable compound as the continuous phase, and forms a liquid film on a support. Thereafter, the curable compound in the liquid film is cured. After curing, the dispersed phase is removed. |
