<p>PROBLEM TO BE SOLVED: To provide a package for storage of an electronic component which can store an electronic part requiring high-speed propagation of a signal in its inside, and operate the stored electronic component normally and besides stably for a long period. SOLUTION: This package comprises an insulating substrate 1, which has a wiring layer 5 where an electronic component 3 is connected and on the top of which a metallic frame 9 is brazed through brazing material 10, and a metallic cover 2, and this is arranged so as store the electric component 3 in its inside by attaching the metallic cover 2 to the metallic frame 9 brazed to the insulating substrate 1. In this case, the insulating substrate 1 is glass ceramics sintered substance of dielectric constant 7 or under and the wiring layer 5 is made of at least one kind of copper, silver, and gold, and besides the brazing material 10 to braze the metallic frame 9 to the insulating substrate 1 is 500 deg.C in fusing point, and also the width of the metallic frame 9 is 0.2-0.5mm, and the thickness is 0.5-1mm, and thickness/width being >=1.</p> |
