A fluorine-containing ether compound represented by formula (1). Formula (1): R1-CH2-R2-CH2-R3 (In formula (1), R1 is a C1-10 alkoxy group, R2 is a perfluoropolyether chain, and R3 represents -OCH2CH(OH)CH2O(CH2)mOH (In the formula, m is an integer which is 2-4.)). L'invention concerne un composé éther fluoré représenté par la formule (1) suivante. Ｒ１－ＣＨ２－Ｒ２－ＣＨ２－Ｒ３　（１） (Dans la formule (1), Ｒ１ représente un groupe alcoxy de 1 à 10 atomes de carbone, Ｒ２ représente une chaîne perfluoroéther, et Ｒ３ représente －ＯＣＨ２ＣＨ（ＯＨ）ＣＨ２Ｏ（ＣＨ２）ｍＯＨ (Dans la formule, m représente un nombre entier de 2 à 4.).) 下記式（１）で表される含フッ素エーテル化合物とする。Ｒ１－ＣＨ２－Ｒ２－ＣＨ２－Ｒ３　（１） （式（１）中、Ｒ１は炭素数１～１０のアルコキシ基であり、Ｒ２はパーフルオロポリエーテル鎖であり、Ｒ３は－ＯＣＨ２ＣＨ（ＯＨ）ＣＨ２Ｏ（ＣＨ２）ｍＯＨ（式中のｍは２～４の整数である。）である。）
