PROBLEM TO BE SOLVED: To provide a fluororesin molded product having a high heat-distortion resistance, and a production method thereof. SOLUTION: A heat resistant fluororesin molded product having a melting point of 325 deg.C or lower and a twisting dynamic elastic modulus at 200 deg.C of 1×10<8> Pa or larger, is produced by applying an ionizing radiation of an exposure does ranging from 1 kGy to 10 MGy to a fluororesin, which is heated to the melting point of the fluororesin or higher, in an inert gas atmosphere wherein the oxygen concentration is 100 Torr or lower. |
