Abstract

The invention relates to an HF ignition device for igniting a fuel in an internal combustion engine with a corona discharge, comprising an ignition electrode, an insulating body on which the ignition electrode is mounted, the insulating body having a continuous channel in which an inner conductor leading to the ignition electrode is disposed, and an outer conductor which encloses the insulating body and, in combination with a section of the inner conductor, forms a capacitor, wherein the channel is filled with an electrically conductive filling material which encloses at least one conductor piece that forms at least one section of the inner conductor.
