Abstract: A method of producing a porous molded part includes a mixing process for mixing a granular porous organizer composed of a water-soluble compound, a porous forming assistant agent composed of a polyhydric alcohol, and a cross-linking agent composed of an organic peroxide with a thermoplastic resin composition having a glass transition temperature below 0° C. to obtain a molding material; a cross-linking and forming process for placing the molding material in a molding die and performing a heat press molding thereby progressing coincidentally a cross-linking reaction and a shape forming of a seal face to obtain a molded material; an extracting process for extracting the granular porous organizer from the molded material obtained in the cross-linking and forming process to obtain a porous molded part; and a drying process for drying the porous molded part obtained in the extracting process.
