Summary: | 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.).
