More Information
Summary:A fluorine-containing ether compound represented by Formula (1) is provided,R1-R2-CH2-R3-CH2-R4  (1)(In Formula (1), R1 is an alkyl group that may have a substituent, R2 is a divalent linking group bonded to R1 via an ethereal oxygen, R3 is a perfluoropolyether chain, and R4 is an end group which is different from R1-R2 and includes two or three polar groups, in which each of the polar groups is bonded to a different carbon atom, and the carbon atoms bonded to the polar groups are bonded to each other via a linking group containing a carbon atom not bonded to the polar groups.).
