PROBLEM TO BE SOLVED: To prevent invasion of concrete into an internal thread part in an insert body, to improve quality and productivity of the insert body, and to prevent damage in sintering of the insert body. SOLUTION: An internal thread member 6 having a through internal thread part 6a and a cap member 7 closing one end of the internal thread member 6 are molded by pressurized molding of material powder. After temporary assembly for placing the internal thread member 6 on the cap member 7, both of them are sintered in a sintering furnace to be integrated together by diffusion binding, and consequently, the insert body constructed of ceramics is provided. |
