摘要： PROBLEM TO BE SOLVED: To provide a coil which is not only excellent in heat shock resistance property but also has high reliability including also shock resistance from the outside in an independent ignition type ignition coil for an internal combustion engine mounted for every ignition plug of the engine and used in direct coupling with each ignition plug. SOLUTION: It is possible to reduce application force followed by moment by altering the shape and material of a cover, and hence to reduce the generated maximum stress. The position of the center of gravity can be lowered by moving the position of a center core to the side of a connector, and hence the moment can be reduced. It is further possible to moderate the generation of internal stress by employing internally elastic soft epoxy, and hence suppress the occurrence of any crack. Thereby, it is possible to reduce the maximum main stress, and possible to prevent the performance from being deteriorated owing to the crack even when any shock is applied.
