This fluorine-containing ether compound is a fluorine-containing ether compound represented by formula (1).R&#x2014;X&#x2014;R&#x2014;CH&#x2014;R&#x2014;CH&#x2014;R&#x2003;&#x2003;(1)(In formula (1), Ris an alkenyloxy group of 2 to 8 carbon atoms or an alkynyloxy group of 3 to 8 carbon atoms. Ris represented by formula (2) shown below. In formula (2), a represents an integer of 1 to 3. X is represented by formula (3) shown below. In formula (3), b represents an integer of 1 to 5, Y is a divalent linking group that is bonded to a carbon atom in formula (2), and R represents an alkyl group of 1 to 6 carbon atoms or H. Rrepresents a perfluoropolyether chain. Rrepresents a terminal group containing two or three polar groups, wherein each polar group is bonded to a different carbon atom, and the carbon atoms to which the polar groups are bonded are bonded to each other via a linking group containing a carbon atom to which a polar group is not bonded.)
