A spark plug for an internal combustion engine has a housing and an insulator held in a clamping area of the housing, which electrically insulates a central electrode from the housing, a heat transfer area having a circumferential gap between the housing and the insulator being provided in the area of a combustion chamber-side end section of the housing for dissipating the heat absorbed by the insulator. The heat transfer area and the clamping area are spatially separated from each other.
