Abstract
A fluorine-containing ether compound represented by the following formula is provided. R1—CH2—R2—CH2—R3—CH2—R4—CH2—R5 (In the formula, R3 is a divalent organic group containing at least one polar group and an alicyclic structure having 3 to 13 carbons, and does not contain a perfluoropolyether chain, R2 and R4 are perfluoropolyether chains, and R1 and R5 are terminal groups containing two or three polar groups, in which individual polar groups are bound to different carbon atoms and the carbon atoms to which the polar groups are bound are bound to each other via a linking group containing a carbon atom to which the polar groups are not bound.)
