A process for fluoropolymer production which is effective in improving the productivity of the emulsion polymerization method while maintaining the excellent material properties of the fluoropolymer, which comprises: (a) a first polymerization step in which a fluoromonomer or a monomer mixture of a fluoromonomer and a nonfluorinated monomer is emulsion-polymerized in the presence of a radical polymerization initiator and an emulsifying agent in an aqueous medium; (b) a dilution step in which the resultant aqueous emulsion of polymer particles is diluted with water to reduce both the number of emulsified polymer particles per unit amount of the aqueous medium and the concentration of the emulsifying agent; and (c) a second polymerization step in which the fluoromonomer and/or nonfluorinated monomer is emulsion-polymerized in the diluted emulsion.
