    • An ignition coil comprises a center magnetic core, a secondary coil wound on a secondary coil bobbin which is arranged at an outer side of said center magnetic core, a primary coil wound on a primary coil bobbin which is arranged at an outer side of said secondary coil. At least one of said secondary coil bobbin and said primary coil bobbin is formed by a, material which contains sulfur in a main chain of an aromatic class. The ignition coil has a superior anti-electric treeing. A coil component of the secondary coil and the primary coil of the ignition coil is arranged and accommodated in a coil case, an epoxy resin filling up at least melting silica is potted and is hardened. A development of the electric treeing can be restrained and the ignition coil having a superior endurance performance can be provided.
    • 点火线圈包括中心磁芯,卷绕在次级线圈架上的次级线圈,其布置在所述中心磁芯的外侧,初级线圈缠绕在初级线圈架上,初级线圈架布置在所述次级线圈的外侧 线圈 所述次级线圈筒管和所述初级线圈筒管中的至少一个由在芳香族主链中含有硫的材料形成。 点火线圈具有优良的抗电树枝。 次级线圈的线圈部件和点火线圈的初级线圈被布置并容纳在线圈壳中,填充至少熔融二氧化硅的环氧树脂被封装并且被硬化。 可以抑制电树枝的发展,并且可以提供具有优异耐久性能的点火线圈。
