Abstract
In an ignition coil for an internal combustion engine, a column section and a notched section are provided in a side wall section of a case section of the ignition coil. A ventilation opening is formed in an up/down direction in the column section. The ventilation opening communicates with a ventilation passage formed between a sealing rubber and the case section and is open in an upper end section. A cover surrounding the column section and covering the upper end section is provided in the side wall section. A sealing section sealing the notched section is provided in the cover. The ignition coil has a filler resin that fills a space within the case section being in continuous contact with the sealing section and the side wall section and fixing the cover to the side wall section.
