ABSTRACT:
A method for producing a ceramic substrate of the present invention includes a first process of providing holes in a shrinkage suppressing layer, a second process of filling the holes with a thick film material, a third process of laminating the shrinkage suppressing layer filled with the thick film material on an outermost layer of a ceramic substrate sintered in a preparatory process, followed by pressing, thereby obtaining a laminate, a fourth process of sintering the laminate, and a fifth process of removing the shrinkage suppressing layer. Thus, the kind of convex portions formed on the outermost layer of the ceramic substrate can be increased.
