Zusammenfassung:	To provide a polyol composition that is excellent in polyurethane moldability (viscosity rise) and foam stability (increase in cell diameter and antifoaming).SOLUTION: A polyol composition contains: a polyol containing a polyalkylene oxide (A) that contains an alkylene oxide residue having three or more carbon atoms with a number average molecular weight of 800 or more as calculated from hydroxyl values and a degree of unsaturation of 0.010 meq/g or less; and an organometallic compound (B) that is at least one selected from the group consisting of Fe compound, Cu compound, Al compound, Mn compound, Ti compound, and Zr compound with its content being 0.1-1000 ppm. The polyol composition is liquid at room temperature.SELECTED DRAWING: None 【課題】ポリウレタン成形性（粘度上昇）ならびに整泡性（気泡径の上昇及び消泡）に優れるポリオール組成物を提供する。【解決手段】炭素数３以上のアルキレンオキシド残基を含有し、水酸基価より算出された数平均分子量が８００以上で、不飽和度が０．０１０ｍｅｑ／ｇ以下であるポリアルキレンオキシド（Ａ）を含むポリオールと、Ｆｅ化合物、Ｃｕ化合物、Ａｌ化合物、Ｍｎ化合物、Ｔｉ化合物、Ｚｒ化合物からなる群より選ばれる１種以上の有機金属化合物で、その含有量が０．１～１０００ｐｐｍの範囲である有機金属化合物（Ｂ）を含み、室温で液状であることを特徴とするポリオール組成物。【選択図】なし
