Abstract:
An individual ignition type ignition coil is adopted to an engine having a plastic head cover. A secondary coil is positioned at an inner side of a primary coil and between a secondary bobbin and a center core a soft epoxy resin is filled up. The soft epoxy resin hash a dent according t a compression molding and has a glass transition point Tg which satisfies a specified condition. The secondary bobbin is formed by PPS and the primary bobbin is set to the primary coli at outer side of the secondary assembling body and under an assembling condition the winding is carried out.
