ABSTRACT:
A nonsintered ceramic body is prepared. A hole is formed in the nonsintered ceramic body. A rod is inserted into the hole. The rod has large- and small-diameter portions within the area facing to the hole. The ceramic body is sintered while the rod is inserted into the ceramic body. By this sintering, the ceramic body is brought into tight contact with the rod by utilizing shrinkage of the ceramic body. The resultant structure is cooled. As a result, the large diameter portion of the rod presses a projection of the ceramic body extending inside the hole by a shrinkage difference due to the difference between the thermal expansion coefficients of the ceramic body and the rod. At least part of the ceramic body is brought into tight contact with at least part of the rod. The rod closes the hole of the ceramic body and the rod is fixed in the ceramic body.
