Abstract
The present invention provides a fluorine-containing ether compound that can form a lubricating layer which has excellent wear resistance even if the thickness is thin and in which a decrease in film thickness due to spin-off is less likely to occur. The fluorine-containing ether compound is represented by the following formula. R—R—O—CH—R—CH—O—R—R(Ris a perfluoropolyether chain. Rand Rare either an alkyl group which may have a substituent or a hydrocarbon group having a double bond or triple bond. Rand Rare each a divalent linking group containing one or more heteroatoms, and have one or more polar groups, and the terminal end on the side bonded to Rand Ris a heteroatom. At least one of Rand Rcontains one or more secondary amine structures. At least one of R—R— and —R—Rcontains one or more cyano groups).
