PROBLEM TO BE SOLVED: To provide a manufacturing method for appropriately crimping the area between the layers of a green sheet laminate while accurately retaining a product shape in the manufacture of a ceramic wiring board. SOLUTION: A cavity 11 is formed as a sheet side recessed section that is open at the uppermost layer of the green sheet laminate 20 where a plurality of ceramic green sheets (a first layer 16, a second layer 14, and a third layer 12) are laminated, and a flexible elastic member 2 where a constant projection pattern is formed on the surface is overlapped to the green sheet laminate 20 so that the side of the projection pattern is located at the side of the recessed pattern. Then, by pressing the green sheet laminate 20 in the lamination direction by the flexible elastic member 2, the green sheet laminate 20 is pinched by the flexible elastic member 2 and a tool 40, and at the same time an elastic member side projection 4 is forcibly deformed when the projection 4 that does not correspond to the sheet side recessed section (cavity 11) is generated for allowing the elastic member side projection 4 to enter the cavity 11, thus crimping the area between the layers of the green sheet laminate 20. |
