A method for producing pellets capable of forming an ion-exchange membrane with excellent electrolytic voltage stability, pellets and an ion-exchange membrane are provided. The method for producing the pellets is as follows: a melt containing a fluoropolymer having groups convertible to ion-exchange groups is extruded from a die of a melt extruder to obtain a strand containing the fluoropolymer, and then the strand is cut to obtain pellets containing the fluoropolymer. When extruding the melt containing the fluoropolymer from the die, the temperature of the die is less than 200°C, and the ion-exchange capacity of the fluoropolymer when the groups convertible to ion-exchange groups are converted into ion-exchange groups is 1.1 meq/g resin or more.
