摘要： A fluorine-containing ether compound of the present invention is represented by Formula (1). R1—CH2—R2—CH2—R3  (1) (In Formula (1), R1 is an organic end group having 3 or more carbon atoms which includes two or more 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 the carbon atoms which are not bonded to the polar groups, R2 includes a perfluoropolyether chain represented by Formula (3), and R3 is a hydroxyl group or R1) —(CF2)y−1—O—((CF2)yO)z—(CF2)y−1—  (3) (In Formula (3), y represents an integer of 2 to 4, and z represents an integer of 1 to 30).
