PROBLEM TO BE SOLVED: To provide a binder for producing an inorganic sintered body, which can provide a ceramic green sheet which is excellent in adhesive property at hot-pressing and pyrolytic property and has enough mechanical strength and flexibility especially in the case of using it as a binder for a ceramic green sheet, as well as a paste for producing an inorganic sintered body, a ceramic green sheet and a ceramic laminate using the binder for producing an inorganic sintered body.SOLUTION: A binder for producing an inorganic sintered body contains a graft copolymer having a unit containing a polyvinyl butyral and a unit containing poly(meth)acrylic acids and the polyvinyl butyral has the polymerization degree of 800 to 5000, the hydroxyl group content of 20 to 40 mol% and the degree of butyralization of 60 to 80 mol%, and the glass transformation temperature of the unit containing poly(meta)acrylic acids is 0 to 110°C. |
