Abstract
Provided is a melt processible fluororesin molded article with reduced metal ions after molding (eluted metal ions) and submicron size fine particles. The melt processible fluororesin molded article has an amount of eluted Ni ions (in pg/cm) and amount of eluted Cr ions (in pg/cm) and amount of eluted Mo ions (in pg/cm) in a test solution after eluting for 20 hours at 60° C. using 12% nitric acid, quantitatively analyzed by the ICP (induced coupled plasma) mass analysis method, satisfy the following formula: wherein Mrefers to the eluted Cr ion amount (in pg/cm), Mrefers to the eluted Mo ion amount (in pg/cm), and Mrefers to the eluted Ni ion amount (in pg/cm).
