ABSTRACT:
An ignition coil, for use particularly in the ignition of an automotive internal combustion engine, includes a central magnetic core member on each side of which is arranged at least one magnetic current return circuit member and two windings, one of which is a primary winding and the other a secondary winding, arranged coaxially around the central magnetic core member. The primary and secondary windings and the central magnetic core member are arranged within an inner casing and covered with synthetic resin. An outer casing encloses the assembly thus formed and surrounded wholly or partially by the magnetic current return circuit member.
