ABSTRACT OF THE DISCLOSURE "A HIGH TENSION COIL ASSEMBLY" A high voltage coil assembly in which a bobbin of a primary winding is interposed, in the vicinity of the both ends thereof, between an iron core and a casting made of an insulating synthetic resin, where the primary winding as well as a secondary winding and auxiliary elements are covered by the casting to be fixedly supported and to ensure insulation. The bobbin of the primary winding is made of a thermoplastic resin so that the shape thereof slightly changes when heat from the windings is applied thereto. Deformation of the bobbin prevents stress from being applied to the casting, where stress occurs due to the difference in thermal expansion and contraction coefficients between the iron core and the casting.
