Abstract:
A spark plug, comprising:a partially cylindrical insulator element; a housing enclosing the partially cylindrical insulator element; a connection including at least one material bond by which the partially cylindrical insulator element and the housing are connected to one another; and an interlayer produced prior to the connection and by which the partially cylindrical insulator element and the housing are connected with one another, wherein: the interlayer is one of applied and attached to the partially cylindrical insulator element; the interlayer is attached to the housing using at least one material bond; a gap is located between the housing and the interlayer in a region of a section lying closer to a base part of the partially cylindrical insulator element; and the interlayer is connected to the housing in a second section further away from the base part.
