Disclosed is a method for producing a high-purity fluorine-containing ether by a simple process at low cost, wherein a side reaction forming unsaturated bonds is suppressed.  When a fluorine-containing ether is produced by reacting a fluorine-containing alkyl alcohol with a fluorinated olefin in the presence of a basic compound, the reaction is stopped before the conversion rate of the fluorine-containing alkyl alcohol exceeds 75%. La présente invention concerne un procédé simple et bon marché permettant la production d'éther fluoré de grande pureté tout en évitant les réactions secondaires donnant lieu à la formation de liaisons insaturées. En l'occurrence, pour produire l'éther fluoré, on utilise un alcool alkylique fluoré que l'on fait réagir avec une oléfine fluorée en présence d'un composé basique, et on arrête la réaction avant que le taux de conversion de l'alcool alkylique fluoré ne dépasse 75%.
