Abstract
An ignition coil device has a plug cap engaging a spark plug; a secondary coil surrounding the plug cap; a primary coil coaxially surrounding the secondary coil; a cylindrical case with a bottom surrounding the plug cap, the secondary coil and the primary coil; and a sealing member for sealing an opening of the case. Furthermore, the coil ends of the primary coil extend close to a bottom of the case and are individually connected to terminals which extend substantially perpendicular to a longitudinal axis of the spark plug. The coil ends and the external wiring are not passed through the sealing member, thereby improving the sealability of the ignition coil. Further, because the coil ends and the external wiring do not interfere with the sealing member, they are not worn by vibrations, thereby improving the durability of the external wiring.
