An ignition unit included in the ignition system of an internal combustion engine includes a plurality of fingerlike connection pieces (2) extending from a common upper part (4) in the ignition unit and connectible to a corresponding number of spark plugs in the engine, the upper part including components included in a high-tension block, each connection piece (2) including an ignition element (20) with an ignition coil for generating ignition voltage, and a connection device (22) for connecting and for transmitting high-tension current to the engine spark plugs. To achieve reliable voltage transmission each ignition element has cable-free electrical connection both to contact means (47) in the upper part (4) and to contact means (27) in its connection device (22).
