Zusammenfassung:	To provide a method for manufacturing a porous body of water-insoluble polymer which is excellent in convenience.SOLUTION: A method for manufacturing a porous body of water-insoluble polymer disclosed here includes the steps of: preparing a solution in which water-insoluble polymer is disposed in a mixed solvent containing a good solvent for the water-insoluble polymer and a poor solvent for the water-insoluble polymer; and vaporizing and removing the mixed solvent from the solution. A boiling point of the poor solvent is higher than a boiling point of the good solvent. Vacancies are formed to obtain the porous body by vaporizing and removing the mixed solvent.SELECTED DRAWING: Figure 1 【課題】簡便性に優れる、非水溶性高分子の多孔質体の製造方法を提供する。【解決手段】ここに開示される非水溶性高分子の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。前記貧溶媒の沸点は、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１
