Abstract

In an ignition coil for an internal combustion engine, a coil case includes a housing section and a high-voltage tower section. The housing section houses a primary coil, a secondary coil, a center core, and an outer peripheral core, and is arranged outside a plug hole in a cylinder of an internal combustion engine in which an ignition plug is arranged. The high-voltage tower section protrudes from the housing section, and is disposed within the plug hole. A pole joint is disposed within the plug hole, and is mounted to the high-voltage tower section via a seal rubber. The pole joint is provided with a rib that protrudes to an outer periphery and faces an inner peripheral surface of the plug hole. The inner peripheral side of the rib faces the high-voltage tower section via the seal rubber.
