Fluorine-containing ether compound, lubricant for magnetic recording medium, and magnetic recording medium

A fluorine-containing ether compound represented by Formula (1),

• R1—CH2—R2[—CH2—R3—CH2—R2]x—CH2—R4 (1)
• (in Formula (1), x represents 1 or 2;
• R2 is a perfluoropolyether chain;
• (x+1) pieces of R2's may be partially or entirely the same as or different from each other;
• R3 is a divalent linking group represented by Formula (2);
• in a case where x is 2, two R3's may be the same as or different from each other;
• R1 and R4 are each a terminal group having 1 to 50 carbon atoms, which has 1 to 4 polar groups;
• and R1 and R4 may be the same as or different from each other)
• (in Formula (2), a1 and a2 each represent an integer of 0 to 5;
• a1 and a2 may be the same as or different from each other, and at least one of a1 and a2 is 1 or more;
• b represents 0 or 1;
• Y is an acyclic divalent saturated hydrocarbon group having 2 to 8 carbon atoms;
• the saturated hydrocarbon group is a partially fluorinated saturated hydrocarbon group which does not include an ether oxygen atom between carbon atoms, or a non-fluorinated saturated hydrocarbon group which may include an ether oxygen atom between carbon atoms and may have only one polar group, provided that in a case where the non-fluorinated saturated hydrocarbon group has the polar group, the polar group is bonded to a carbon atom other than a bonding terminal of Y;
• and an oxygen atom at a left terminal of Formula (2) is bonded to a methylene group on an R1 side in Formula (1), and an oxygen atom at a right terminal is bonded to a methylene group on an R4 side in Formula (1)).
