To provide a production method that efficiently removes an aluminum catalyst possibly having an adverse effect when used as a raw material for polyurethane.SOLUTION: A method for producing a halogen-containing polyether polyol or a halogen-containing polyether ester polyol includes following (A) and (B) steps. In the (A) step, a catalyst composition including onium salt, Lewis acid and active hydrogen-containing compound is used for the polymerization reaction of alkylene oxide, to produce a crude halogen-containing polyether polyol or a crude halogen-containing polyether ester polyol. In the (B) step, the crude halogen-containing polyether polyol or crude halogen-containing polyether ester polyol produced in the (A) step is subjected to addition of polysaccharides and water and the mixture is heated and stirred.SELECTED DRAWING: None 【課題】 ポリウレタン原料として用いた際に影響を及ぼす可能性のあるアルミ触媒を効率よく除去する製造方法を提供する。【解決手段】 以下の（Ａ）工程、及び（Ｂ）工程を含むハロゲン含有ポリエーテルポリオールまたはハロゲン含有ポリエーテルエステルポリオールの製造方法。（Ａ）工程；オニウム塩、ルイス酸及び活性水素含有化合物を含む触媒組成物を用いて、アルキレンオキシドの重合反応を行い、粗ハロゲン含有ポリエーテルポリオールまたは粗ハロゲン含有ポリエーテルエステルポリオールを製造する工程。（Ｂ）工程；（Ａ）工程により得られた粗ハロゲン含有ポリエーテルポリオールまたは粗ハロゲン含有ポリエーテルエステルポリオールに、多糖類および水を添加し加熱攪拌する工程。【選択図】 なし
