PROBLEM TO BE SOLVED: To provide a method for manufacturing a 2-phenoxyethanol reaction liquid of high purity which is not accompanied by the change in a basic catalyst and dispenses with a solvent. SOLUTION: In the manufacture of the 2-phenoxyethanol reaction liquid of high purity by reacting phenol with ethylene oxide in the absence of a solvent and in the presence of a basic catalyst, an addition reaction is carried out while feeding ethylene oxide until the molar ratio of ethylene oxide to phenol reaches 0.90-1.02, and the basic catalyst is partially neutralized. Then, ethylene oxide is supplementarily fed until the molar ratio of ethylene oxide to phenol reaches 1.04-1.08 to continue the addition reaction, and the residual catalyst is post-treated.
