Abstract
A spark plug with a longitudinal axis. The spark plug includes a housing; an insulator disposed at least partly inside the housing; a center electrode disposed at least partly inside the insulator and having a base body and a first ignition element; and at least one ground electrode disposed inside the housing and having a base body and a second ignition element. The ground electrode and the center electrode are disposed such they form a spark gap which extends radially with respect to the spark plug longitudinal axis. A surface of the first ignition element of the center electrode which serves as ignition surfaces and a surface of the second ignition element of the ground electrode which serves as ignition surfaces are flat surfaces. A width of the spark gap is not greater than 0.3 mm, and the spark gap is formed inside the housing.
