A feed-through component for a conductor feed-through which passes through a part of a housing, for example a battery housing, is embedded in a glass or glass ceramic material and has at least one conductor, for example an essentially pin-shaped conductor, and a head part. The surface, in particular the cross-sectional surface, of the head part is greater than the surface, in particular the cross-sectional surface, of the conductor, for example of the essentially pin-shaped conductor. The head part is embodied such that is can be joined to an electrode-connecting component, for example an electrode-connecting part, which may be made of copper, a copper alloy CuSiC, an aluminum alloy AlSiC or aluminum, with a mechanically stable and non-detachable connection.
