Abstract
Provided is a fluorine-containing ether compound represented by Formula (1). R1—CH2—R2—CH2—R3 (1) R2 represents a perfluoropolyether chain. R1 and R3 represent an end group having one to four polar groups and 1 to 50 carbon atoms. At least one of R1 or R3 represents an end group represented by Formula (2). —O—X—CH(OH)—CH2OH (2) X represents a divalent organic group having 2 to 30 carbon atoms, which may have at least one of one or two polar groups or one to three ether oxygen atoms. X has at least one carbon atom which is not bonded to any of the polar groups and the ether oxygen atoms.

A fluorine-containing ether compound which is represented by Formula (1),
- (in Formula (1), R2 represents a perfluoropolyether chain;
- R1 and R3 represent an end group having one to four polar groups and 1 to 50 carbon atoms;
- R1 and R3 may be the same as or different from each other;
- and at least one of R1 or R3 represents an end group represented by Formula (2)),
- (in Formula (2), X represents a divalent organic group having 2 to 30 carbon atoms, which may have at least one of one or two polar groups or one to three ether oxygen atoms;
- and X has at least one carbon atom which is bonded to neither of the polar groups nor the ether oxygen atoms).
