Abstract
An internal combustion engine ignition device has a resin layer in a clearance between an insulator and a winding contained in the insulator. The ignition device has a cylindrical insulator and a resin layer. The insulator has an opening portion at one end and a bottom portion at the other end. The insulator contains one of a primary winding and a secondary winding. The resin layer is formed by charging a resin in the clearance between the insulator and one of the windings. The diameter of the inner periphery of the insulator gradually increases from the opening portion to the bottom portion. When the resin layer shrinks from the opening portion toward the bottom portion of the insulator, the resin layer can shrink without getting snagged on the inner periphery of the insulator.
