The present invention has an object to provide a fluorine-containing compound which can be used for applications such as additives making a transparent resin material low in a water absorbing ratio and high in water repellency without deteriorating of various properties such as transparency which the transparent resin material has, a fluorine-containing ester compound which is superior in properties such as heat resistance and low moisture(water) absorption property and can be suitably used in various fields such as a material for electronic information, a material for precision instruments and an optical material, a fluorine-containing aryl ester polymer, methods of producing the same. The present invention provides a fluorine-containing compound represented by the following formula (1):
in the formula, X represents an oxygen atom or a sulfur atom; Rf represents a fluorine-containing alkyl group having 4 or more carbon atoms; r represents the number of Rf—X— groups bonded to an aromatic ring and is an integer of 1 or more; s represents the number of fluorine atoms bonded to an aromatic ring and is an integer of 1 or more; and r+s is an integer of 2 to 5.
