ABSTRACT:
An ignition coil is equipped with a sparkplug of an engine. The ignition coil includes a coil portion, a tower portion, and a plug cap. The coil portion includes a coil case accommodating a primary and secondary coils being coaxial with each other. The coil portion has an end connected with the plug cap via the tower portion. The plug cap is press-fitted with the sparkplug. The coil case has an outer periphery from which a flange portion projects radially outward in a flange-projecting direction. The tower cylinder portion has a tower axis substantially in parallel with a coil axis of the primary and secondary coils. The tower axis is offset from the coil axis in a tower-offset direction. The tower-offset direction is substantially the same as the flange-projecting direction.
