Abstract: A method for manufacturing a porous film includes: a first step of preparing droplets (D) which are formed from a first liquid into spheres with a predetermined diameter of 10 μm or more and 2000 μm or less and a second liquid (L2) which includes a curing agent which cures by imparting energy or a curing agent which cures due to change in pH and includes droplets dispersed therein; a second step of injecting the droplets and the second liquid into a gap between a pair of substrates (31 and 32); a third step of curing the second liquid to form an external phase; and the fourth step of removing the droplets in the external phase to form hole sections.
