PROBLEM TO BE SOLVED: To provide a method capable of producing a thermoplastic resin molding having continuous pores without forming a skin layer with a shape of a molding in such a wide range that a porosity is 20-95 vol.%. ! SOLUTION: There is provided a method for producing a thermoplastic resin continuous pore body which includes: mixing 0-100 pts.wt of a hydrophilic solvent with respect to 100 pts.wt of a mixture in which a volume ratio of a thermoplastic resin and a pore-forming agent that are granular is 5: 95 to 80: 20 at such a temperature that the thermoplastic resin particles are not softened by heat and the pore-forming agent does not decompose or melt, and dissolve in the hydrophilic solvent; inserting the obtained mixture into a mold for molding, molding the mixture while holding the mixture at such a temperature that the thermoplastic resin particles are softened by heating and the pore-forming agent does not decompose or melt, and dissolve in the hydrophilic solvent, and obtaining a molded |
