<P>PROBLEM TO BE SOLVED: To improve sealing performance and reinforce a sealing structure. <P>SOLUTION: The aggregate of ceramics and metal is provided with a ceramic tube 1, a metal plate 2, and a sealing structure 3 linking the ceramic tube (1) and the metal plate 2. The sealing structure 3 consists of a sealing layer 5, intercalated between the ceramic tube 1 and the metal plate 2, a first ring 4, intercalated between the sealing layer 5 and the metal plate 2, and a second ring 11 as a part of the metal plate 2, intercalated between the first ring 4 and the metal plate 2. The sealing layer 5 has an adhesive force toward the ceramic tube 1 and the first ring 4. The second ring 11 has a curved surface 7 smoothly bent in a center line L direction L of the ceramic tube 1. The curved surface 7 is in planar contact or linear contact with respect to the first ring 4 in terms of pressure. The curved surface 7 is formed by bending the metal plate 2. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
