A high-purity alcohol compound can be obtained by a method comprising passing a solution containing an ester compound and methanol and/or ethanol through a column packed with an anion exchange resin having methoxide and/or ethoxide as a counter anion to generate a methyl ester and/or ethyl ester, and distilling off the methyl ester and/or ethyl ester together with the methanol and/or ethanol.
