The invention relates to a corona ignition device for igniting fuel in an internal combustion engine by means of a corona discharge, comprising a central electrode, an insulator, into which the central electrode plugs, a housing, into which the insulator plugs, a bobbin, onto which a coil which is attached to the central electrode is wound, and a shield cap, which is plugged onto an end portion of the bobbin facing the insulator. According to the invention, a portion of the central electrode protrudes through a bottom of the shield cap, or a circumferential wall of the shield cap has one or more slots, or the shield cap has a circumferential wall, which protrudes only on one side beyond the bottom of the shield cap only on one side.
