Abstract
An ignition coil for an internal-combustion engine has satisfactory electrical insulation capacity and is excellent in reliability and durability. The ignition coil for an internal-combustion engine comprises a primary bobbin on which a primary coil is wound, a secondary bobbin on which a secondary coil is wound, and a center core. The area of a cross section of the center core perpendicular to an axis of the coils at a position on the inner side of the opposite ends of the center core is a maximum.
