A method of producing a porous molded body from an emulsion including a continuous phase and a dispersed phase, the method comprising: a three-dimensionalization step of placing the emulsion including a water phase containing a curable compound as the continuous phase in a container; a curing step of curing the curable compound in a state in which the emulsion is placed in the container to form a cured product; a peeling step of separating the container and the cured product; and a dispersed phase removal step of removing the dispersed phase of the cured product after the peeling 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 molding material preparation step having 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 the uneven distribution region generated in the emulsion base is used as the emulsion. a three-dimensionalization step of placing the emulsion including a water phase containing a curable compound as the continuous phase in a container; a curing step of curing the curable compound in a state in which the emulsion is placed in the container to form a cured product; a peeling step of separating the container and the cured product; and a dispersed phase removal step of removing the dispersed phase of the cured product after the peeling 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 molding material preparation step having 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 the uneven distribution region generated in the emulsion base is used as the emulsion. a molding material preparation step having 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 the uneven distribution region generated in the emulsion base is used as the emulsion.
