Claim 18:
19. The fluorinated ether compound according to claim 18, wherein Qf is a group represented by the following formula (g1b):

—Rf4—(ORf2)m(ORf3)n—  (g1b)

wherein Rf2 is a C1-6 fluoroalkylene group provided that to the carbon atom at the terminal on the Q2 side of Rf2 bonded to Q2, at least one fluorine atom is bonded,
Rf3 is a bivalent fluorinated hydrocarbon group having a fluorinated cyclic structure provided that to the carbon atom at the terminal on the Q2 side of Rf3 bonded to Q2, at least one fluorine atom is bonded,
Rf4 is a C1-6 fluoroalkylene group or a bivalent fluorinated hydrocarbon group having a fluorinated cyclic structure provided that to the carbon atom at the terminal on the Q2 side of Rf4, at least one fluorine atom is bonded,
n is an integer of from 0 to 500 when Rf4 has a fluorinated cyclic structure, or an integer of from 1 to 500 when Rf4 has no fluorinated cyclic structure, and when n is at least 2, (ORf3)n may consist of two or more types of ORf3,
when n is 0, m is an integer of from 5 to 500, and
when n is at least 1, m is an integer of from 2 to 500,
provided that when m is at least 2, (ORf2)m may consist of two or more types of ORf2, and
the bonding order of m (ORf2) and n (ORf3) is not limited.
