To provide a method capable of producing a high purity fluorine- containing alcohol with less t-butanol contents.

This method for producing the fluorine-containing alcohol expressed by the following formula (1): H(CF2CF2)nCH2OH in the presence of an organic peroxide generating t-butanol by its decomposition and an acid- accepting agent comprises the steps of (i) reacting tetrafluoroethylene with methanol; (ii) removing the reaction product of the acid-accepting agent and the unreacted acid-accepting agent from the obtained crude reaction product; and (iii) heating the crude reaction product treated with the above (ii) process under an acidic condition for separating the fluorine-containing alcohol of the formula (1).
