Claim:
1. A corona ignition device, comprising: a center electrode; an insulator surrounding the center electrode; a coil connected to the center electrode; a housing pipe in which the coil is arranged, the housing pipe comprising a substrate layer and a conducting layer arranged radially inwardly of the substrate layer, the conducting layer being supported by the substrate layer to thereby form a composite tubular pipe, the conducting layer having a thickness of at least 0.1 mm and being made of a material having a greater electrical conductivity than the material of the substrate layer; and wherein the substrate layer of the housing pipe is produced from sheet metal, to which the conducting layer has been applied by roll cladding and a longitudinally extending weld secures the substrate layer and conducting layer in a tubular form.
