Abstract
A spark plug is described having a partially cylindrical insulator element and a housing surrounding the insulator element on the side of a base part. The insulator element and the housing are connected with one another by at least one material bond and/or one friction-lock connection aligned in the radial direction. A compact spark plug can be produced using this type of connection. In particular, the diameter of the spark plug is smaller than the diameter of known spark plugs having the same characteristics.
