Abstract
The invention relates to 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 needles, and a housing, into which the insulator plugs. In accordance with the invention, the ignition needles and the center electrode plug into the ignition head. The invention also relates to a method for producing an ignition head for a corona ignition device, wherein a green compact of the ignition head is produced by injection molding of metal powder, and the green compact is sintered while ignition needles and/or a center electrode plug thereinto.
