摘要： An ignition coil includes primary and secondary coils accommodated in a coil case extending to define a cylindrical mount portion on a high voltage side. The mount portion includes a high voltage terminal electrically connected with the secondary coil. A coil spring electrically connects the high voltage terminal with a sparkplug. An electrically insulative plug cap is attached to the mount portion. The coil spring has a low voltage end electrically connected with the secondary coil via the high voltage terminal. The coil spring has a high voltage end in contact with a terminal of the sparkplug. The coil spring has an intermediate portion between the low voltage end and the high voltage end. The plug cap has a spring support portion, which is partially defining the fitting hole and restricting the intermediate portion of the coil spring from being radially deformed.

摘要： A primary coil of an ignition coil has a socket with a side wall having an opening, a center core having a body portion with a root located in the opening and a collar portion extending perpendicularly from the root, and a winding wound on the body portion while the socket catches start and end portions of the winding on respective winding start and end sides. The collar portion is held in the socket. The core is formed by compressing magnetic powder in two divided dies divided through dividing lines which extend along a diagonal line of a rectangle formed by projecting the collar portion on a plane perpendicular to a center axis of the core. The root on the diagonal line is exposed to the opening on the winding start side and is covered with the side wall on the winding end side.
