Zusammenfassung:	To provide a method for producing a resin porous body using a water-insoluble polymer which is excellent in simplicity and can suppress formation a skin layer.SOLUTION: A method for producing a resin porous body includes: a step of preparing a coating liquid in which a water-insoluble polymer is dissolved and insulating particles are dispersed in a mixed solvent containing a good solvent for the water-insoluble polymer and a poor solvent for the water-insoluble polymer; a step of applying the coating liquid onto a base material; and a step of removing the mixed solvent from the applied coating liquid by vaporizing. A boiling point of the poor solvent is higher than a boiling point of the good solvent. The mixed solvent is removed by vaporizing to form voids, thereby obtaining a porous body.SELECTED DRAWING: Figure 2 【課題】簡便性に優れ、かつスキン層の形成を抑制可能な、非水溶性高分子を用いた樹脂多孔質体の製造方法を提供する。【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中に、前記非水溶性高分子が溶解し、かつ絶縁粒子が分散した塗工液を調製する工程と、前記塗工液を、基材上に塗工する工程と、前記塗工された塗工液から、前記混合溶媒を気化させて除去する工程と、を包含する。前記貧溶媒の沸点が、前記良溶媒の沸点よりも高い。前記混合溶媒を気化させて除去することによって、空孔を形成して多孔質体を得る。【選択図】図２
