Summary:To provide a binder composition for molding ceramics capable of suppressing occurrence of a residue during thermal decomposition and useful for producing a ceramic slurry excellent in stability and useful for producing a ceramic molding (in particular, green sheet) excellent in smoothness and flexibility.SOLUTION: A binder composition for molding ceramics comprises a component (A) and a component (B), wherein the component (A) is a specific copolymer between a monomer (a) that is a specific polyalkylene glycol mono(meth)acrylate monomer and another copolymerizable monomer (b), and a component (B) is a phthalate ester and/or a compound represented by the formula: R2O-(AO2)q-(AO3)r-H (where, symbols in the formula are as defined in the specification). The mass ratio of the amount of the component (A) and the amount of the component (B) is from 15/85 to 95/5.SELECTED DRAWING: None 【課題】熱分解での残渣の発生を抑制でき、且つ安定性に優れたセラミックスラリーを製造するため、並びに平滑性および柔軟性に優れたセラミックス成形体（特に、グリーンシート）を製造するために有用な、セラミックス成形用バインダー組成物を提供すること。【解決手段】成分（Ａ）および成分（Ｂ）を含むセラミックス成形用バインダー組成物であって、成分（Ａ）が、特定のポリアルキレングリコールモノ（メタ）アクリレートであるモノマー（ａ）とその他の共重合可能なモノマー（ｂ）との特定の共重合体であり、成分（Ｂ）がフタル酸エステルおよび／または式：Ｒ２Ｏ－（ＡＯ２）ｑ－（ＡＯ３）ｒ－Ｈ（式中の記号の定義は明細書に記載した通りである）で表される化合物であり、並びに成分（Ａ）の量と成分（Ｂ）の量との質量比が１５／８５～９５／５であるセラミックス成形用バインダー組成物。【選択図】なし
