摘要：
An ignition coil for the internal combustion engine has a cylinder portion and a head portion. A pillar portion that forms a part of a ventilation passage that communicates inside and outside of a plug hole via a sealing member, and a cover portion that covers the pillar portion without blockading an upper opening of a ventilation opening of the pillar portion are formed on a side of the head portion.
