The invention relates to a glow plug comprising a housing, a ceramic pencil-type glow element which projects from the housing with a first end and is arranged inside the housing with a second end, a feed line which is arranged in the housing and leads to the pencil-type glow element, and a sleeve-type element which surrounds a section of the pencil-type glow element projecting from the housing. The invention is characterized in that the pencil-type glow element has a section surrounded by the housing which section tapers towards the second end, the pencil-type glow element is encircled by a contact element in the housing, which contact element has a section that narrows towards the second end of the pencil-type glow element, said narrowing section encircling at least a subsection of the tapered section of the pencil-type glow element. The invention further relates to a method for producing said glow plug.

Glow plug

Composite conductor comprising a metallic conductor and a ceramic conductor or non-conductor, at least one of them being elongate, the two being connected with each other in an electrically conductive manner. The ceramic conductor or non-conductor and the metallic conductor are hard-soldered to each other by a contact surface extending obliquely to the longitudinal direction of the at least one elongate conductor, and has one of the conductors tapers at its end and the other conductor has a matching tapering recess. The tapering end of the conductor is fitted into the tapering recess.
