A first diode has its anode connected to a capacitor, and its cathode connected between the first end of the secondary coil, at which a high positive voltage is generated upon interruption of the primary current, and a high voltage output terminal at a secondary coil first end side. A second diode has its anode connected to the secondary coil first end, and its cathode connected to a junction between the first diode and the high voltage output terminal.

摘要： An ignition coil for an internal combustion engine with a compact height and width includes an actuated magnetic portion of an iron core around which a primary coil is wound having an axis line crossing an ignition plug axis line of the internal combustion engine at a right angle; and a switching unit which is disposed at an end of the actuated magnetic portion vertically to the axis line of the actuated magnetic portion and intercepts a primary current flowing through the primary coil. This ignition coil can be manufactured at a greatly reduced cost, compared to the conventional ignition coil in which only one of the height or width is made compact, by reducing the required size of the press mold for the case and by reducing the initial investment for the equipment.
