To provide a method for producing a melt-processable fluororesin, which is capable of increasing the molecular weight of the fluororesin and preventing coloration of the fluororesin, by using a specific fluorinated emulsifier other than ammonium perfluorooctanoate. A method for producing a melt-processable fluororesin which is characterized in that a fluorinated monomer is emulsion-polymerized in an aqueous medium containing a fluorinated emulsifier of a formula (1) XCF.sub.2CF.sub.2(O).sub.mCF.sub.2CF.sub.2OCF.sub.2COOA wherein X is a hydrogen atom or a fluorine atom, A is a hydrogen atom, an alkali metal or NH.sub.4, and m is an integer of 0 or 1.
