The present invention provides an excellent thermal property and thermal decomposition property, and in particular, when used as a binder for a ceramic green sheet, a ceramic green sheet having sufficient mechanical strength and flexibility can be obtained. A binder for producing an inorganic sintered body, a paste for producing an inorganic sintered body using the binder for producing the inorganic sintered body, a ceramic green sheet, and a ceramic laminate. The present invention relates to a binder for producing an inorganic sintered body, which comprises a graft copolymer having a unit composed of polyvinyl butyral and a unit composed of poly(meth)acrylic acid, The degree of polymerization of polyvinyl butyral is 800 to 5000, the amount of hydroxyl groups is 20 to 40 mol%, and the degree of butyralization is 60 to 80 mol%, and the above-mentioned unit composed of poly(meth)acrylic acid The glass transition temperature is 0~110 °C. |
