Zusammenfassung:	To provide a binder composition for forming a mold capable of forming a mold excellent in strength and dimensional accuracy and of inhibiting the generation of formaldehyde odor when forming a mold or making a casting.SOLUTION: A binder composition for forming a mold contains water-soluble phenolic resin and monoamine. In the binder composition for forming a mold, the monoamine essentially requires primary monoamine or secondary monoamine, and the nitrogen content of the binder composition for forming a mold is 0.05-0.40 mass%.SELECTED DRAWING: None 【課題】強度、及び寸法精度に優れた鋳型を造型することができ、鋳型造型時や鋳物製造時のホルムアルデヒド臭の発生を抑制することができる鋳型造型用粘結剤組成物を提供すること。【解決手段】水溶性フェノール樹脂及びモノアミンを含有する鋳型造型用粘結剤組成物であって、前記モノアミンが１級モノアミン又は２級モノアミンを必須とするものであり、前記鋳型造型用粘結剤組成物中の窒素含有量が０．０５〜０．４０質量％である、鋳型造型用粘結剤組成物。【選択図】なし
