摘要：

The present invention provides a method for readily and efficiently manufacturing a ceramic substrate having an excellent dimensional accuracy and small degree of warp comprising the steps of: preparing a non-sintered multilayer ceramic body formed by laminating ceramic layers and conductor layers; forming a multilayer ceramic body with constraint layers by adhering a first constraint layer and a second constraint layer on one major surface and the other major surface, respectively, of the multilayer ceramic body, the first and second constraint layers being prepared by dispersing a ceramic powder that is not sintered under the sintering condition of the multilayer ceramic body; firing the multilayer ceramic body with the constraint layers under the firing condition of the multilayer ceramic body; and removing the first constraint layer and the second constraint layer after sintering the multilayer ceramic body, wherein the thickness of the first constraint layer is made to be larger than the thickness of the second constraint layer, and the first constraint layer is provided on one major surface that is more largely contracted by firing.
