The present invention relates to a package for a high-frequency device, in which the characteristic impedance can be matched while a gap between the casing and each terminal is maintained wide enough to avoid contact. In the package for a high-frequency device, each metallic terminal is hermetically fixed to a conductive casing and is electrically insulated from the conductive casing by glass. Each metallic terminal extends in parallel with a side wall of the conductive casing while it is separated from the side wall. Each metallic terminal is also flanked by a pair of conductive protruding portions that are formed on a side wall of the conductive casing and extend in the longitudinal direction of each metallic terminal. The conductive protruding portions are formed on either side of each metallic terminal and serve to match the characteristic impedance.

1. A package for a high-frequency device, comprising:a plurality of metallic terminals that are insulated from a conductive casing by glass and are hermetically fixed to the conductive casing by glass, each of the plurality of metallic terminals extending outward from said casing then downward in parallel with a side wall of the conductive casing and being separated from the side wall; and a conductive U-shaped protruding portion having a base portion and leg portions, said protruding portion formed on either side of each metallic terminal with said leg portions extending out from said base portion in the longitudinal direction of each downward extending portion of said metallic terminal, each of the conductive U-shaped protruding portions being separated from said metallic terminal and surrounding the glass-fixed portion of said metallic terminal extending outward from the conductive casing, and each of the conductive U-shaped protruding portions serving to match characteristic impedance.
