A novel production method for producing a fluoropolymer by polymerizing tetrafluoroethylene and vinylidene fluoride is provided. A method for producing a fluoropolymer comprising the step of polymerizing tetrafluoroethylene and vinylidene fluoride in the presence of a surfactant and an aqueous medium, wherein the surfactant comprises the formula: CX 2 = CFCF 2- O— (CF (CF 3 ) CF 2 O) n —CF (CF 3 ) —Y (wherein each X is the same or different and represents F or H. n is an integer of 0 or 1 to 10) Y represents —SO 3 M or —COOM, and M represents H, NH 4 or an alkali metal.), And fluorine-containing fluorine having 7 or less carbon atoms A production method, which is a mixture of an anionic surfactant (excluding the fluorine-containing allyl ether compound).
