Provided is a method for producing a porous molded body that can produce a porous molded body having excellent texture and texture, large porosity, and sufficient strength at low cost. SOLUTION: To 100 parts by weight of a granular material obtained by pulverizing porous natural stone, 10 to 50 parts by weight of a vinyl acetate aqueous resin emulsion and 1 to 20 parts by weight of a crosslinking agent are mixed, and this kneaded product is pressure-molded. The molded body obtained in this way is housed in a microwave permeable container such as glass, ceramic, paper, etc. and irradiated with microwaves from the outside to evaporate the water in the vinyl acetate aqueous resin emulsion in a short time.
