Abstract
Ceramic cavitiesandhave upper and lower open faces and contain dielectric coresandformed integrally therein. The ceramic cavitiesandare sandwiched between upper and lower panelsandat the upper and lower open faces, respectively, of the ceramic cavitiesandvia grounding platesandand grounding platesand, respectively, and the upper and lower panelsandare fixed by screws. Based on this structure, a problem of an unreliable joint part between an open face of a ceramic cavity and a metal panel connected directly to each other by soldering and the problem of increase of the number of components of a structure in which a printed circuit board is mounted to the open face of the ceramic cavity by using grounding plates can be overcome, even when the ceramic cavity has an open face formed in a complex shape.
