In a green laminate including a plurality of base green layers and a plurality of restraint green layers for forming the monolithic ceramic substrate of the present invention using a non-shrinkage process, when the thicknesses of the plurality of base green layers are different from each other. The thick base green layer shrinks greatly during the sintering process. Therefore, in some cases, warpage may occur in the obtained monolithic ceramic substrate. In order to solve this problem, the thickness of the constraint green layer in contact with the main surface of each base green layer is different. That is, the relatively thick restraint green layer is in contact with the relatively thick base green layer, and the relatively thin restraint green layer is in contact with the relatively thin base green layer. |
