Abstract
An ignition coil apparatus for an internal combustion engine can suppress an increase in the manufacturing cost of a terminal of a low-tension side connector resulting from variation in a wire diameter of an one end of a primary winding, and can ensure a stable fusing state. The positive terminal side fusing portion is composed of a planar portion and a turned portion that is inversely turned back from the planar portion to cooperate therewith to clamp a winding start conductor portion. A first bent portion of a radius of curvature R is formed at a base end portion of the turned portion. A second bent portion with its tip end tilted toward a planar portion is formed at an intermediate portion of the turned portion.
