Claim:
1. A method for producing a fluoropolymer, comprising aqueous dispersion polymerization in an aqueous dispersion polymerization medium of a fluoroolefin in the presence of a compound (1) represented by formula (1): wherein R wherein the aqueous dispersion polymerization of the fluoroolefin is carried out together with a non-fluorinated vinyl monomer and a non-fluorinated monomer having a crosslinkable group, wherein the non-fluorinated monomer having a crosslinkable group is an unsaturated carboxylic acid, wherein the amount of the compound (1) is 500 to 50000 ppm based on the amount of water in the aqueous dispersion polymerization medium, and wherein the non-fluorinated vinyl monomer is at least one selected from the group consisting of vinyl ethers and vinyl esters.
