The invention relates to a corona ignition device. The device has a center electrode (5) connected with an insulator (3). A coil (7) is connected to the center electrode. The coil is arranged in a housing tube (1). The housing tube provides a support layer (1a) and a conductive layer (1b) that is arranged radially inwardly of the support layer. The support layer is made of a material with a higher electrical conductivity than the material of the support layer, where the thickness of the conductive layer is in the range of 0.1 m. The conductive layer is covered by a protective layer i.e. lacquer layer. 本发明涉及种电晕点火装置，其包括中心电极(5)、围绕中心电极(5)的绝缘体(3)、连接至中心电极(5)的线圈(7)、以及壳体管(1)，线圈(7)布置在壳体管(1)中，其中壳体管(1)包括基底层(1a)和导电层(1b)，导电层(1b)布置在基底层(1a)的径向内侧，并且其中导电层(1b)由具有比基底层(1a)的材料大的电导率的材料制成。根据本发明，导电层(1b)具有至少0.1mm的厚度。本发明还涉及用于制造电晕点火装置的方法，其中，为了制造壳体管(1)，将内管插入外管中。本发明还涉及线圈(7)由软磁屏蔽围绕的电晕点火装置。
