PROBLEM TO BE SOLVED: To provide a method for producing a polyether alcohol in the presence of a DMC catalyst by using an Si-H-containing compound as an additive. SOLUTION: The method for producing a polyether alcohol by polymerization uses a composite metal cyanide catalyst (DMC catalyst), wherein one or more optionally mixed additives selected from among compounds, each having at least one hydride hydrogen atom bonded to one silicon atom, is added to the reaction mixture before or during the polymerization.
