An ignition coil (1) for internal-combustion engines has a magnetic core (8) and a primary and secondary winding (2, 3) surrounding said core (8), and standardised connections (5, 6, 7) for the windings (2, 3) on a housing. In order to improve the electrical and mechanical strength of the ignition coil (1), with simplified production and compact construction of the ignition coil (1), windings (2, 3) have casting compound cast around them as a completely round part (4), or are inserted into a completely round part (4) and, with this, have casting compound cast around them, the core (8) is constructed as a double-U shaped core whose one limb (9) is surrounded by the windings (2, 3), with an air gap (10), and whose other limb (13) is arranged outside the completely round part (4), attachment brackets (14) for the ignition coil being fitted on the other limb (13), and the completely round part (4) having recesses (11, 15, 16) for holding the core (8), with the exception of the outer limb (13), into which the core (8) is inserted in a force-fitting manner. The core (8) is advantageously connected to the completely round part (4), in a vibration-resistant manner, by means of casting compound. <IMAGE>
