Summary: | Provided is a method for manufacturing a sheet-shaped separation membrane that allows a sheet-shaped separation membrane having uniform separating ability to be manufactured at a high speed, the method comprising manufacturing a sheet-shaped separation membrane by forming a microporous layer on a porous substrate, wherein the method is characterized in having: a membrane-forming solution application step of coating a porous substrate with a membrane-forming solution in which a polymer is dissolved in a solvent, a congealing liquid application step of applying a congealing liquid by a liquid membrane drop method to the porous substrate coated with the membrane-forming solution, and a solvent removal step of removing the solvent from the congealed microporous layer. |
