A novel perfluoropolyether derivative which is less likely to undergo decomposition, which is free from a problem of deterioration during its use, and which is useful as a lubricating oil or a coating agent, is provided. A compound represented by the following formula (1):HO&#x2014;(CHCHO). (CHCH(OH)CHO)&#x2014;CHCFO(CFCFO)CFCHO&#x2014;&#x2014;(CHCH(OH)CHO). (CHCHO)&#x2014;H &#x2003;&#x2003;Formula (1)wherein m represents an integer of from 3 to 200, and each of p, q, r and s which are independent of one another, represents an integer of from 0 to 100, provided that when each of p, q, r and s which are independent of one another, is an integer of at least 1, the arrangement of &#x2014;(CHCHO)&#x2014; and &#x2014;(CHCH(OH)CHO)&#x2014; units is not particularly limited, and when one of r and p is an integer of at least 2 and the other is an integer of at least 1, or when one of q and s is an integer of at least 2 and the other is an integer of at least 1, these units may be arranged in a block form or at random.
