Beschreibung
Zusammenfassung:	A spark plug includes a housing, an isolator arranged in the housing, and a ground electrode arranged on a front surface of the housing on a combustion chamber side. The spark plug further includes a central electrode, a terminal stud, and a resistance element all of which are arranged in the isolator. The resistance element is spatially arranged between the central electrode and the terminal stud and connects the central electrode to the terminal stud. The ground electrode forms a spark gap together with the central electrode. The resistance element contains a resistance material that contains conductive particles and non-conductive particles. At least 80% of the non-conductive particles have a maximum diameter of 20 μm.
