Zusammenfassung:	To provide a method for producing a resin porous body which suppresses formation of a skin layer using a water-insoluble polymer through a small number of processes.SOLUTION: A method for producing a resin porous body includes: a step of preparing a solution obtained by dissolving a water-insoluble polymer in a mixed solvent containing a good solvent of the water-insoluble polymer and a poor solvent of the water-insoluble polymer; and a step of drying the solution and removing the mixed solvent. A boiling point of the poor solvent is higher than a boiling point of the good solvent. The solution is dried using superheated steam.SELECTED DRAWING: Figure 1 【課題】非水溶性高分子を用いて、少ない工程数で、スキン層の形成が抑制された樹脂多孔質体を製造可能な方法を提供する。【解決手段】ここに開示される樹脂多孔質体の製造方法は、非水溶性高分子の良溶媒および前記非水溶性高分子の貧溶媒を含有する混合溶媒に、前記非水溶性高分子が溶解した溶液を調製する工程と、前記溶液を乾燥して前記混合溶媒を除去する工程と、を包含する。前記貧溶媒の沸点は、前記良溶媒の沸点よりも高い。前記溶液の乾燥を、過熱水蒸気を用いて行う。【選択図】図１
