Abstract
The invention provides a process for producing a modified molded article capable of providing a diaphragm that is less likely to generate particles. The process for producing a modified molded article includes: molding modified polytetrafluoroethylene containing a tetrafluoroethylene unit and a modifying monomer unit based on a modifying monomer copolymerizable with tetrafluoroethylene to provide a molded article; and irradiating the molded article with not lower than 30 kGy but lower than 70 kGy of radiation at 270° C. to 310° C. to provide a modified molded article.
