A bar-type coil for ignition systems, in particular, for as an ignition coil in internal combustion engines of motor vehicles, is designed to minimize the interference voltage produced by the ignition processes. The bar-type coil has a core, designed as an I-core, a tubular magnetic return plate, and a primary terminal. Mounted in the primary terminal is, in addition to other elements, a first contact element, which is electrically connected to frame potential. The first contact element is part of a line bar, which is electrically connected via a resistance element or via a laminated strip to the tubular magnetic return plate, so that the interference voltage produced is diverted to frame potential. The bar-type coil may be used in automobile manufacturing.
