Disclosed is a method for producing a fluorine-containing polymer wherein an aqueous dispersion of a fluorine-containing polymer can be separated into the fluorine-containing polymer and the moisture content easily and efficiently. Also disclosed is a fluorine-containing polymer obtained by such a production method. Further disclosed is a molded article obtained by crosslinking a curable composition which contains such a fluorine-containing polymer and a crosslinking agent. Specifically disclosed is a method for producing a fluorine-containing polymer including a step wherein a fluorine-containing polymer having a moisture content of not more than 1% by weight is obtained by heating an aqueous dispersion of the fluorine-containing polymer having a concentration of 3-70% by weight.
