Abstract
An ignition coil apparatus for an internal combustion engine can prevent noise from being radiated to the outside from a transformer without requiring special man-hours even if a case takes a complex shape. The ignition apparatus is provided with a transformer () including a primary coil (), a secondary coil () and an iron core, a case () with the transformer () received therein, and an insulating resinfilled in the case (). A high voltage generated at a high voltage side of the secondary coil () upon interruption of a primary current supplied to the primary coil () is impressed to a spark plug (). The case () is made of a conductive plastic.
