Abstract

Provided is a method that can produce a resin porous material from a water-insoluble polymer in a small number of steps while suppressing the formation of skin layers. The production method of a resin porous material disclosed herein includes preparing a solution of a water-insoluble polymer in a mixed solvent including a good solvent of the water-insoluble polymer and a poor solvent of the water-insoluble polymer, and drying the solution to remove the mixed solvent. The poor solvent has a higher boiling point than the good solvent. The drying the solution is performed using superheated water vapor.
