The present invention relates to a method for producing a water-soluble fluorine-containing vinyl ether which comprises subjecting a fluorine-containing 2-alkoxypropionic acid derivative represented by the following general formula (I): <CHEM> (wherein A represents -OM<1> or -OM<2>1/2, and M<1> represents an alkali metal and M<2> represents an alkaline earth metal; X represents a halogen atom; Y<1> and Y<2> are the same or different and each represents a fluorine atom, a chlorine atom, a perfluoroalkyl group or a fluorochloroalkyl group; n represents an integer of 0 to 3, and n of Y<1>s may be the same or different; m represents an integer of 1 to 5, and m of Y<2>s are the same or different; and Z represents a hydrophilic group) to thermal decomposition at a temperature of not lower than 50 DEG C but lower than 170 DEG C in the presence of a coordinating organic solvent to give a water-soluble fluorine-containing vinyl ether represented by the general formula (II): <CHEM> (wherein Y<1>, Y<2>, Z, n and m are as defined above), said coordinating organic solvent having a coordinating property with an ion of said M<1> or an ion of said M<2> said coordinating organic solvent being in an amount of 10 to 1,000 parts by mass per 100 parts by mass of the fluorine-containing 2-alkoxypropionic acid derivative.
