Abstract: An ignition coil (1) comprises a case (2), a core (22) disposed in the case, a primary spool (25) substantially coaxially disposed on the outer periphery of the core in the case, a primary coil (26) wound on the primary spool, a secondary spool (23) substantially coaxially disposed on the outer periphery of the core in the case, a secondary coil (24) wound on the secondary spool, a resin insulator (5) filled into the case, wherein of the primary and secondary spools, the secondary coil and the core and/or the spool between the secondary and primary coils is made of a base resin whose adhesive force on resin insulation material is less than that of polybutylene terephthalate and whose breakdown voltage is greater than that of polyphenylene sulfide.

Abstract: An ignition coil (1) having a case (2), a core (22) installed in the case, a primary spool (25) disposed substantially coaxially around an outer circumference of the core within the case, a primary coil (26) comprising a wire wound around the primary spool, a secondary spool (23) disposed substantially coaxially around the outer circumference of the core within the case, a secondary coil (24) comprising a wire wound around the secondary spool and a resin insulating material (5) filled within the case, the ignition coil being characterized in that the spool of the primary and the secondary spools which is disposed between the secondary coil and the core and/or which is disposed between the secondary coil and the primary coil comprises a base resin having an adhesive strength to the resin insulating material which is less than that provided by polybutylene terephthalate and an insulation breakdown voltage which exceeds that provided by polyphenylene sulfide.
