ABSTRACT:
An ignition coil assembly for an internal combustion engine includes a primary coil, a secondary coil, at least one bobbin, a core, a first resin member and a casing. The primary coil and said secondary coil are wound on the bobbin. The core has core elements with a gap there-between through which the primary and secondary coils are magnetically coupled to one each other. The casing accommodates the primary and secondary coils, the bobbin and the core. And the first resin member covers a part of the core elements, the part which are confronted with said secondary coil, and the first resin member is accommodated in the casing.
