Beschreibung
Zusammenfassung:	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, which has a continuous channel, a central electrode, which plugs into the channel of the insulator and leads to at least one ignition tip, a glass seal, which seals in the channel a gap between the central electrode and the insulator, and a housing, into which the insulator plugs. In accordance with the invention, the central electrode has a sealing face, which, together with a sealing face of the insulator, forms a seat, and an annular air gap that is open towards the ignition tip is provided in an end portion of the channel, facing the ignition tip, between the central electrode and the insulator.
