Abstract

See full text

An ignition coil for internal combustion engines is provided which includes magnetically coupled primary and secondary coils, a case, a high-voltage tower, a resistor, and resin packed in the case. The case has the primary coil and the secondary coil disposed therein. The high-voltage tower is attached to a tower mount formed on a front end of the case. The resistor is embedded in the high-voltage tower with a front and a base end surfaces thereof exposed from the high-voltage tower. The resin is packed in the case to seal the primary coil and the secondary coil. This structure enhances the productivity of an assembly of the high-voltage tower and the resistor.
