A base body for a metal-sealing material-feedthrough subject to high pressures in an igniter for an airbag or a belt tensioning device. The base body for the metal-sealing material feedthrough is an element formed by a process of cold forming and having a ring-shape or a plate-like shape. The element includes a feedthrough opening extending from a front side of the element towards a rear side of the element. There is a metallurgic section in the element of the base body with structure-lines or flow-lines that are bent due to a reshaping process of the process of cold-forming.
