Abstract:
The present invention relates to a fluorine-containing ether compound represented by Formula (1), R1—R2—CH2—R3—CH2—R4 (1). (In Formula (1), R1 is an end group including an organic group having at least one double bond or triple bond, R2 is a divalent linking group bonded to R1 by etheric oxygen, R3 is a perfluoropolyether chain, R4 is an end group having two or three polar groups with each polar group being bonded to different carbon atoms, and the carbon atoms, to which the polar groups are bonded, being bonded to each other via a linking group including carbon atoms to which the polar groups are not bonded.)
