This fluorine-containing ether compound is a fluorine-containing ether compound represented by the following formula:

R.sup.1CH.sub.2R.sup.2(CH.sub.2OCH.sub.2CR.sup.3R.sup.4CH.sub.2OCH.sub.2R.sup.2).sub.zCH.sub.2R.sup.5

(z represents 1 or 2. R.sup.2 is a perfluoropolyether chain. R.sup.1 and R.sup.5 are terminal groups having 1 to 50 carbon atoms and having at least one polar group. R.sup.3 and R.sup.4 may be the same as or different from each other, and are organic groups which do not include a secondary hydroxy group and a tertiary hydroxy group, include one primary hydroxy group, and have 1 to 5 carbon atoms bonded to a tetrasubstituted carbon atom. The organic group may include an ether oxygen atom between the carbon atoms, and a bonding terminal to the tetrasubstituted carbon atom may be an ether oxygen atom.)
