<p>Disclosed is a method for easily and efficiently producing a ceramic molded body having less warping or bending with high dimensional accuracy. There is prepared a laminate wherein a base layer (20) mainly composed of a ceramic material and a glass material, first constraining layers (22a, 22b) mainly composed of a ceramic material which is not sintered at a temperature at which the base layer can be sintered, second constraining layers (24a, 24b) mainly composed of a glass material and a ceramic material which is sintered at a temperature at which the base layer can be sintered, and third constraining layers (26a, 26b) mainly composed of a ceramic material which is not sintered at a temperature at which the base layer can be sintered, are arranged in this order. Next, the laminate is fired at a temperature at which the base layer can be sintered and the first, second and third constraining layers are removed from the laminate after firing, thereby obtaining a ceramic molded body which is a sintered base layer. After the firing, adhesion between the base layer and the first constraining layers and adhesion between the second constraining layers and the first constraining layers are different from each other.</p> |
