摘要： PROBLEM TO BE SOLVED: To adapt an ignition coil device of an independent ignition type to an engine having plastic head covers by enhancing resistance to a thermal shock and the mitigation of an electric-field concentration between a secondary coil and a center core. SOLUTION: The ignition coil has a second coil 3 located inside a primary coil 5 while a soft epoxy 17 is filled between a secondary bobbin 2 and the center core 1. Since the soft epoxy 17 is injected from the low voltage side of the secondary coil, the secondary bobbin 2 is provided with a taper that causes such a difference in the inner diameter that the inner diameter of the secondary bobbin 2 is larger in the low voltage side of the secondary coil and is smaller in the high voltage side so that the thickness of the secondary bobbin is thinner in the low voltage side and is thicker in the high voltage side. The soft epoxy 17 has a recess 17' as a result of pressurized molding. The soft epoxy 17 has a glass transition point Tg (-40°C) that satisfies a condition that the allowable stress of the secondary bobbin is greater than stress generated at the glass transition point Tg (-40°C) of the insulating resin.
