Provided is a treatment method for fluororesin pellets to remove hydrofluoric acid released from fluororesin pellets obtained by melt-molding a melt-moldable fluororesin. The treatment method comprises bringing a hydrofluoric acid-removing medium selected from warm water of from 30 to 200°C, steam of from 100 to 200°C and warm wind of from 40 to 200°C into contact with fluororesin pellets obtained by melt-molding a melt-moldable fluororesin, and thereby treating the fluororesin pellets so that the amount of hydrofluoric acid released per kg of the resulting fluororesin pellets would be at most 5 µg as determined after the storage of the resulting fluororesin pellets at 35°C for 15 days. |
