PROBLEM TO BE SOLVED: To manufacture a ceramic structure having high tensile strength with high working efficiency. SOLUTION: The source powder is press formed by using female screw die tools 11, 12 and press dies 7 to 10 to form a female screw member 13. After the press dies 7 to 10 are removed, the ceramic source powder is press formed around the female screw member 13 by using the female screw die tools 11, 12 and press dies 14 to 17 as attached to form a sheath tube 18. After the female screw die tools 11, 12 and the press dies 14, 17 are removed, the female screw members 13 and the sheath tube 18 are calcined so that the sheath tube 18 presses the female screw member 7 to tightly fix to each other. |
