Abstract: An ignition coil contains an elongated substantially circular coil core which includes a primary coil and a secondary coil each disposed radially outwardly of the core with the core composed of a plurality of generally rectangular elements at least some of which have a different width than others and the elements being in surface-to-surface contact with each other. The lateral walls of the elements may have a shape which is not perpendicular to the longitudinal extent of the elements. The core may be welded at its ends. A core contained within this ignition coil, which may be an automotive ignition coil, is disclosed.
