ABSTRACT:
An ignition coil for an internal combustion engine, having a seal between the ignition coil and a plug hole of the engine. An air passage is provided only on a head portion and a pipe portion of the ignition coil to permit air to pass. Pressure change in the plug hole can be equalized with the atmosphere through the air passage. Therefore, it becomes easy to make the seal and to attach the seal to the ignition coil because the seal does not have any air passage.
