PURPOSE: To obtain the titled sheet which is free from generation of a wrinkle and a crack on the surface in a drying process by using butyl methacrylate resin as an organic binder and using a mixed soln. of methyl isobutyl ketone and isophorone as a solvent.

CONSTITUTION: Slurry consisting of (A) ceramic powder (e.g. alumina powder), (B) an organic binder consisting of butyl methacrylate resin, (C) a solvent consisting of a mixed soln. of methyl isobutyl ketone and isophorone, (D) a plasticizer (e.g. dibutyl phthalate) and (E) a dispersant added in accordance with necessity is prepared. Then this slurry is molded with a doctor blade method and a green sheet for a ceramic substrate is produced. Thereby the dried sheet which is free from a wrinkle and a crack on the surface and homogeneous can be produced without using a specific drying means even in the case of a thick-walled sheet.
