JOINED BODY MANUFACTURING METHOD AND JOINED BODY
공정(a)에서는, 세라믹스 기체(12)보다 열팽창계수가 큰 금속으로 이루어진 브레이징재(56)와, 브레이징재(56)보다 열팽창계수가 작은 다공질체(54)와, 급전 단자(40)를, 급전 단자(40)의 접합면(43)이 세라믹스 기체(12)의 접합면(13)과 대향하도록 접합면(13) 상에 배치한다. 공정(b)에서는, 브레이징재(56)를 용융시켜 브레이징재(56)를 다공질체(54)의 기공 내에 침투시켜 브레이징재(56)와 다공질체(54)를 포함하는 접합층을 형성하고, 접합층을 통해 세라믹스 기체(12)의 접합면(13)과 급전 단자(40)의 접합면(43)을 접합한다.
In a step (a), a ceramic substrate, a brazing material including a metal having a large thermal expansion coefficient, a porous body having a smaller thermal expansion coefficient than the brazing material, and a feeding terminal are placed on a joint surface in such a way that a joint surface of the feeding terminal faces a joint surface of the ceramic substrate. In a step (b), the brazing material is fused to allow the brazing material to penetrate into the pores of the porous body. In this manner, a joint layer containing the brazing material and the porous body is formed, and the joint surface of the ceramic substrate and the joint surface of the feeding terminal are joined to each other through the joint layer.
