Abstract
The invention relates to a corona ignition device for igniting fuel in a combustion chamber of an engine by means of a corona discharge, comprising an insulator, a center electrode, which plugs into the insulator and carries an ignition head having a plurality of ignition tips, a coil, which is connected to the center electrode, and a housing, which surrounds the coil and into which the insulator plugs, wherein the ignition head has main body formed from sheet metal. In accordance with the invention, the ignition tips consist of a different material compared to the main body and are fastened to a side face of the main body. The invention also relates to an ignition head for such a corona ignition device and to a method for production thereof.
