A fluorine-containing ether compound which is represented by R1-R2-CH2-R3-CH2-R4-R5. (In the formula, R3 represents a perfluoropolyether chain; each of R1 and R5 independently represents an optionallysubstituted alkyl group, an organic group having at least one double bond or triple bond, or a hydrogen atom; -R2-CH2-R3 is represented by formula (2); and R3-CH2-R4- is represented by formula (3).)-[A]-[B]-O-CH2-R3 (2) R3-CH2-O-[C]-[D]- (3) (In formulae (2) and (3), [A] is represented by formula (4); [B] is represented by formula (5); [C] is represented by formula (6); and [D] is represented byformula (7). In formulae (4) to (6), each of a and b represents an integer of 0-2; c represents an integer of 2-5; each of d and f represents an integer of 0-2; e represents an integer of 2-5; and atleast one of b and d is 1 or more.). R-R-CH-R-CH-R-R所示的含氟醚化合物。(R为全氟聚醚链；R和R各自独立地为可以具有取代基的烷基、具有至少一个双键或三键的有机基、氢原子中的任一者；-R-CH-R由式(2)表示，R-CH-R-由式(3)表示。)-[A]-[B]-O-CH-R(2)R-CH-O-[C]-[D]-(3)([A]由式(4)表示，[B]由式(5)表示，[C]由式(6)表示，[D]由式(7)表示
