PURPOSE: To produce a homogeneously porous body of an aliphatic ester-amide copolymer resin in no need of a noxious and strongly pollutive solvent. CONSTITUTION: An aliphatic ester-amide copolymer resin is dissolved or dispersed in a solution of a metal salt in a water-containing or water-free organic solvent. Then, the organic solvent is removed from the mixture, subsequently the metal salt is removed by using water or an aqueous solution to give the objective porous body of an aliphatic ester-amide copolymer resin with a density of 0.2-l.0g/cm<3> . |
