A ceramic portion (2) is inserted in the front side of the housing envelope (1) by shrinking. At the joint resp. the junction (4) of these parts, a sealing layer, preferably a galvanized copper layer, is ap- plied which ensures a connection which under the resulting pressure is impermeable to gases and humid- ity. The ceramic portion (2) is exposed to a strong radial pressure prestress with the result that the tensile stress of the ceramic portion is reduced and thus the pressure resistance thereof is increased under the effect of an axially acting external pres- sure.
