Abstract
A spark plug with an improved heat-dissipating capacity of the center electrode. The spark plug includes a ground electrode, a center electrode and a ceramic insulator, which is designed to accommodate the center electrode. The center electrode has a center-electrode head which lies in the direction of an electrical connection region of the spark plug and which includes an end face that is in contact with an electrically conductive connection element disposed between the electrical connection region and the center-electrode head. At its outer periphery, the center-electrode head is at least regionally in heat-conducting contact with the ceramic insulator and forms a heat-conducting contact region.
