This method for producing a polyether polyol produces a polyether polyol by reacting a cyclic ether with an initiator which has a melting point of 150°C or less, while comprising 8 or more functional groups in the presence of a catalyst. Ce procédé de production d'un polyéther polyol produit un polyéther polyol par réaction d'un éther cyclique avec un initiateur qui a un point de fusion de 150 °C ou moins, tout en comprenant 8 groupes fonctionnels ou plus, en présence d'un catalyseur. 官能基数が８以上であり、且つ、融点が１５０℃以下である開始剤と、環状エーテルとを、触媒の存在下で反応させて、ポリエーテルポリオールを製造する、ポリエーテルポリオールの製造方法。
