Abstract
A ceramic sheathed-element glow plug includes a ceramic glow element made of an electrically conductive layer and an electrically insulating layer, in which the conductive layer is made of supply layers and a heating layer. The higher specific electrical resistance of the heating layer allows the temperature of the heating layer and of the combustion chamber to be determined, and the electrical contact between a connecting element and the glow element is established by a contacting element that is composed of a pellet made of an electrically conductive powder.
