PURPOSE: A polyoxyalkylene polyol and manufacturing method for the same is provided, in which C=C is low even when an alkylene oxide is addition polymerized to an active hydrogen compound and made into a high molecular weight, H-T bond selectivity is high, and the molecular weight distribution of the polyol of the main reaction component is sharp. CONSTITUTION: A polyoxyalkylene polyol, its manufacture method, and derivatives are obtained using a phosphazenium compound as a catalyst, wherein the hydroxyl value is 2-200 mgKOH/g; total degree of unsaturation is 0.0001-0.07 meq/g; the head-to-tail bond selectivity of the polyoxyalkylene polyol is 95 mole %; and when the maximum height of the peak of GPC elution curve is set to be 100 %, W20 is defined as the peak width at the 20% peak height, and W80 is defined as the peak width at 80 % peak height, the ratio of W20/W80 is 1.5 or greater, and less than 3.
