英文摘要	In a semiconductor device which has an air tight metal package containing a high frequency wave range circuit element and which has a waveguide-coaxial line transformation structure, a metal terminal for the waveguide-coaxial line is air-tightly attached directly in a hole of a base of the metal package with a dielectric spacer, usually by glass fusion, whereby the thickness of the base may be reduced and attachment of the terminal to the base is simplified.
