Abstract: Processes for producing a fluorinated ether compound are provided by which fluorinated ether compound capable of imparting excellent water/oil repellency, to a substrate surface or a hard coat layer can be easily produced in high yield. A process comprising reacting Rf(CF2)a—CF2OC(═O)Rf4 or Rf(CF2)a—C(═O)X1 with HN(—R1CH═CH2)2 to obtain Rf(CF2)a—C(═O)N(—R1CH2═CH2)2 and a process comprising obtaining the above product and reacting the product with HSiR2nL3−n to obtain Rf(CF2)a—C(═O)N(—R1CH2CH2SiR2nL3−n)2 wherein Rf is a linear polyfluoroalkyl group having at least two carbon atoms and at least one etheric oxygen atom between carbon atoms, Rf4 is a C1-30 perfluoroalkyl group or the like, X1 is a halogen atom, R1 is an alkylene group, a is an integer of from 1 to 5, R2 is a monovalent hydrocarbon group, L is a hydrolyzable group, and n is an integer of from 0 to 2.
