description To provide an ignition coil in which cracking in a filling body is prevented.SOLUTION: An ignition coil 2 comprises: a primary coil 20; a secondary coil 24 formed outside the primary coil 20; and an annular iron core unit 32. The iron core unit 32 comprises: a central iron core 26 penetrating the primary coil 20; an outer peripheral iron core 28 which has a contact surface 52 making contact with the central iron core 26, and which extends one end of the central iron core 26 and goes around the outside of the secondary coil 24; and a cover 30 made of an elastomer. The contact surface 52 has an exposed part 62 which protrudes further outside than the central iron core 26 in the axial direction of the iron core unit 32. The cover 30 has a protruding part 68 which covers the exposed part 62.SELECTED DRAWING: Figure 3 【課題】充填体でのクラックの発生が防止された、点火コイルの提供。【解決手段】この点火コイル2は、一次コイル20と、前記一次コイル20の外側に形成された二次コイル24と、環状の鉄芯ユニット32とを備える。前記鉄芯ユニット32は、前記一次コイル20を貫通する中央鉄芯26と、前記中央鉄芯26と接触する接触面52を有し前記中央鉄芯26の一方の端から延び前記二次コイル24の外側をまわる外周鉄芯28と、エラストマーからなるカバー30とを備える。前記接触面52が、前記鉄芯ユニット32の軸方向において前記中央鉄芯26よりも外側に突出した、露出部62を有している。前記カバー30は、前記露出部62を覆う突出部68を有している。【選択図】図3
