Abstract
There is provided a fluorine-containing ether compound represented by the following formula: wherein R3 and R4 are the same or different perfluoropolyether chains; R2 and R5 are each independently a divalent linking group having one or more polar groups; R1 and R6 are each independently an end group containing a tertiary amine, and represented by —X—NR7R8 (X is a divalent hydrocarbon group having 1 to 5 carbon atoms; R7 and R8 are the same or different saturated aliphatic groups; and R7 and R8 may form a ring structure together with a nitrogen atom).
