A metal fixing material leadthrough for igniters of airbags and/or belt tighteners includes at least one metal pin fused into a glass or glass-ceramic fixing material in a through-opening of a main body. The metal is present in a post-heated state, with an interface between the fixing material and the metal pin and an additional interface between the fixing material and an inner surface of the through-opening. The at least one metal pin, at least in its core region, consists of stainless steel, such as a chromium-containing stainless steel, the stainless steel having a thermal expansion coefficient.
