Abstract
A method for manufacturing a ceramic plate-shaped body that efficiently manufactures a ceramic plate-shaped body having high smoothness without requiring polishing after firing. The method includes preparing an unsintered plate-shaped body, preparing a plurality of resin sheets by a resin slurry containing a spherical resin powder that is composed of a resin material being poorly-soluble in an organic solvent and burning out during firing, producing an unsintered laminate by laminating and press-bonding the unsintered plate-shaped body and the resin sheet, firing the unsintered laminate so that the unsintered plate-shaped body is sintered to form a ceramic plate-shaped body, and the ceramic plate-shaped bodies are bonded to each other with scattered fine bonding portions interposed therebetween to form a ceramic laminate, and breaking the bonding portions in the ceramic laminate so that the ceramic laminate is divided into a plurality of ceramic plate-shaped bodies.
