    • A small-sized heat resisting high voltage transformer and an ignition transformer using the high voltage transformer are provided and utilize both a heat resistant casting resin and a bobbin, which contain an inorganic filler. The high voltage transformer is capable of producing an output voltage of 10-35 kV and comprises a primary coil, a secondary coil, and a magnetic core, wherein a casting resin is injected into the coil part and subsequently cured. The casting resin and bobbin material used for making the coils have heat distortion temperature of at least 130° C., and contain an inorganic filler. The surface of the bobbin may be pretreated. Thereby, adhesion between a bobbin and a casting resin is enhanced to ensure operating properly under the sever heat cycle condition and provide a small-sized heat resistant high voltage transformer.

    • To improve an anti-heat shock performance and an electric field concentration relaxation (an insulation performance) between a secondary coil and a center core, to attain a narrow diameter structure in an individual ignition type ignition coil and further to improve an assembling working of the ignition coil. The individual ignition type ignition coil is adopted to an engine having a plastic head cover. A secondary coil 3 is positioned at an inner side of a primary coil 5 and between a secondary bobbin 2 and a center core 1 a soft epoxy resin 17 is filled up. In the secondary bobbin 2, a secondary coil low voltage side is a potting side of the soft epoxy resin 17 and an inclination having a difference in an inner diameter is provided on the inner diameter in which the secondary coil low voltage side is formed large and secondary coil high voltage side is formed small. In the secondary bobbin, a thickness in the secondary coil low voltage side is formed thin and a thickness in the secondary coil high voltage side is formed thick. The soft epoxy resin 17 has a dent 17′ according to a compression molding and has a glass transition point Tg which satisfies a condition of [an allowable stress of the secondary bobbin > a generation stress at (from −40° C. to a glass transition point of an insulation resin)]. The secondary bobbin is formed by PPS and the primary bobbin is set to the primary coil at outer side of the secondary assembling body and under an assembling condition the winding is carried out.
