Abstract

Provided are a method for producing ceramic green sheets used for making a ceramic substrate which is reduced in cracking failure and improved in adhesion between laminated layers and is high in lamination property, high in strength and excellent in surface roughness, said method including heat-treating the ceramic powder having a specific particle size by dry grinding a ceramic powder to prepare ceramic powder having a specific average degree of aggregation and preparing a slurry using the ceramic powder so that a green density of the resulting ceramic green sheets is in a desired range, and a method for making a ceramic laminated substrate having excellent various properties by laminating the above ceramic green sheets and firing the laminate.
