Abstract

PURPOSE:To increase the airtightness and to reduce the cost of products, by realizing a cold weld with a case by taking the material of the base as ''Kovar ''. CONSTITUTION:Holes 13 and 13 to which lead wires 17 and 17 are inserted are made on an upper part 12 of a base 11 formed with ''Kovar '' and projections 14 for cold weld are provided to an opening side ridges. Sintering glass 16 is filled in an inside space 15 of the base 11 to fix the leads 17 and 17. A case 20 made of nickel or aluminum is formed with projections 22 for cold weld at the open ridge of a package 21. The lower surface of the projections 14 of the base 11 is overlapped on the upper surface of the projections 22 of the case 20 and the overlapped part is welded with cold welding.
