摘要： A spark plug is disclosed which is used for an internal combustion engine such as an automobile. The spark plug has a carbonaceous resistance sandwiched between its spark rod electrode and its terminal rod in the central through hole of an elongated hollow cylindrical ceramic insulator. The spark electrode is made of a heat and spark resisting semiconductive resistance material, is sealed integrally with the carbonaceous resistance in the central through hole of the insulator, and produces a spark discharge between a grounded electrode spaced therefrom by a predetermined gap. The spark plug of the above-mentioned construction enables the intensity of a noise wave produced upon the spark discharge to be suppressed to the lowest possible level.
