Abstract
The present invention provides a binder for manufacturing an inorganic sintered body that has excellent adhesiveness upon heat pressing and thermal decomposability and, especially when used as a binder for a ceramic green sheet, provides a ceramic green sheet having sufficient mechanical strength and flexibility. The present invention also provides a paste for manufacturing an inorganic sintered body, a ceramic green sheet, and a ceramic laminate individually manufactured using the binder for manufacturing an inorganic sintered body. The present invention provides a binder for manufacturing an inorganic sintered body containing a graft copolymer having a unit including polyvinyl butyral and a unit including a poly(meth)acrylic compound, the polyvinyl butyral having a polymerization degree of 800 to 5000, a hydroxy group content of 20 to 40 mol %, and a butyralization degree of 60 to 80 mol %, the unit including a poly(meth)acrylic compound having a glass transition temperature of 0 to 110° C.
