Apparatus and method for manufacturing ceramic laminate

Abstract

The space between a material sheet laminate 105 and the inner wall of a processing chamber 13a is filled with a buffer material. The material sheet laminate is heated in a firing furnace while the material sheet laminate is pressurized through the buffer material in a way of reducing the volume of a processing chamber 13a by loading of a weight 17. In this way, the material sheet laminate 105 is fired which it is pressurized from all the directions through the buffer material 14. This suppresses the warp of a ceramic laminate 100 due to the densification phenomenon occurring during the step of firing the material sheet laminate 105, thereby providing the ceramic laminate 100 with no warp.
