A method of producing a porous molded body from an emulsion including a continuous phase and a dispersed phase, the method comprising: a film forming step of forming a film on a support from the emulsion including a water phase containing a curable compound as the continuous phase; a curing step of curing the curable compound after the film forming step; and a dispersed phase removal step of removing the dispersed phase of the film after the curing step, wherein in the emulsion, in a case where a volume of the dispersed phase is X1 and a volume of the continuous phase is X2, a value of X1/(X1 + X2) is within a range of 0.5 or more and 0.9 or less, and a specific gravity of the dispersed phase is greater than a specific gravity of the continuous phase, wherein the method further comprises: a base production step of discharging a first liquid forming the dispersed phase as a liquid droplet in a flow of a second liquid forming the continuous phase from a distal end of a tubular member in a direction of the flow of the second liquid to produce an emulsion base having a value of X1/(X1 + X2) smaller than that of the emulsion; and an uneven distribution step of unevenly distributing the dispersed phase in the emulsion base to generate an uneven distribution region having a value of X1/(X1 + X2) within a range of 0.5 or more and 0.9 or less in the emulsion base, wherein in the film forming step, the uneven distribution region generated in the emulsion base is used as the emulsion. a film forming step of forming a film on a support from the emulsion including a water phase containing a curable compound as the continuous phase; a curing step of curing the curable compound after the film forming step; and a dispersed phase removal step of removing the dispersed phase of the film after the curing step, wherein in the emulsion, in a case where a volume of the dispersed phase is X1 and a volume of the continuous phase is X2, a value of X1/(X1 + X2) is within a range of 0.5 or more and 0.9 or less, and a specific gravity of the dispersed phase is greater than a specific gravity of the continuous phase, wherein the method further comprises: a base production step of discharging a first liquid forming the dispersed phase as a liquid droplet in a flow of a second liquid forming the continuous phase from a distal end of a tubular member in a direction of the flow of the second liquid to produce an emulsion base having a value of X1/(X1 + X2) smaller than that of the emulsion; and an uneven distribution step of unevenly distributing the dispersed phase in the emulsion base to generate an uneven distribution region having a value of X1/(X1 + X2) within a range of 0.5 or more and 0.9 or less in the emulsion base, wherein in the film forming step, the uneven distribution region generated in the emulsion base is used as the emulsion. a base production step of discharging a first liquid forming the dispersed phase as a liquid droplet in a flow of a second liquid forming the continuous phase from a distal end of a tubular member in a direction of the flow of the second liquid to produce an emulsion base having a value of X1/(X1 + X2) smaller than that of the emulsion; and an uneven distribution step of unevenly distributing the dispersed phase in the emulsion base to generate an uneven distribution region having a value of X1/(X1 + X2) within a range of 0.5 or more and 0.9 or less in the emulsion base, wherein in the film forming step, the uneven distribution region generated in the emulsion base is used as the emulsion. <EOS>
