Claim 1:
2. The fluorinated ether compound according to claim 1, wherein Rf is a group represented by the following formula (g1a):

Rf1—(ORf2)m(ORf3)n—  (g1a)

wherein Rf1 is a C1-20 fluoroalkyl group or a monovalent fluorinated hydrocarbon group having a fluorinated cyclic structure,
Rf2 is a C1-6 fluoroalkylene group provided that to the carbon atom at the terminal on the Q1 side of Rf2 bonded to Q1, 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 Q1 side of Rf3 bonded to Q1, at least one fluorine atom is bonded),
n is an integer of from 0 to 500 when Rf1 has a fluorinated cyclic structure, or an integer of from 1 to 500 when Rf1 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.
