A production method for a fluorine-containing ether compound that makes it possible to form a surface layer that has excellent abrasion resistance and suppressed particle generation; and a production method for an article. A production method for a fluorine-containing ether compound, the production method involving reacting, in the presence of a hydrosilylation catalyst, a compound that has a poly(oxyperfluoroalkylene) chain and a ω-alkenyl group and a compound that has a hydrogen atom that is bonded to a silicon atom and also has a hydrolyzable group that is bonded to a silicon atom and/or a hydroxyl group that is bonded to a silicon atom to produce a fluorine-containing ether compound that has a poly(oxyperfluoroalkylene) chain and also has a hydrolyzable group that is bonded to a silicon atom and/or a hydroxyl group that is bonded to a silicon atom. The production method is characterized in that, after the fluorine-containing ether compound has been obtained, the fluorine-containing ether compound is brought into contact with an adsorbent that has a water content of no more than 1.0 mass%, or a reaction is performed in the presence of a hydrosilylation catalyst and an adsorbent that has a water content of no more than 1.0 mass%.
