Abstract
An ignition coil for an internal combustion engine has a rod-shaped magnetic core, which is situated within a secondary coil shell. The annular interspace between the magnetic core and the secondary coil shell is filled with an electrically insulating molded material. To prevent the formation of tears in the molded material during thermo-mechanical loading, or the spread of such tears such that the operativeness of the ignition coil is adversely affected, a separation element is provided, which divides the molded material into at least two mutually separate regions.
