摘要:
Provided is a fluorine-containing ether compound capable of forming a lubricant layer having excellent wear resistance even when the thickness is thin, and suitable as a material of a lubricant for a magnetic recording medium. The fluorine-containing ether compound is a compound represented by the following formula (1): R1—R2—CH2—R3—CH2—R4—R5; wherein R3 is a perfluoropolyether chain; R1 is a terminal group bonded to R2; R5 is a terminal group bonded to R4; R1 is an alkenyl group or an alkynyl group; R5 is a group containing a heterocyclic ring; R2 is represented by the following formula (2); R4 is represented by the following formula (3); and a in the formula (2) and b in the formula (3) are each independently an integer of 1 to 3.
