PROBLEM TO BE SOLVED: To provide a polyurethane foam which can suppress the generating amount of volatile organic compounds (VOC) from the formed polyurethane foam and from various its products in use of them, by such a method that selectively using a polymer compound having at least a prescribed number average molecular weight. SOLUTION: The polyurethane foam is obtained by blending a polyol, an isocyanate, a catalyst and an antioxidant. Wherein the generating amount of the volatile organic compounds from the formed polyurethane foam, is suppressed by applying the polymer compound having at least the prescribed number average molecular weight to both such antioxidant uses that one is the above-described antioxidant and the other is for the polyol, being used at synthesizing the polyol.
