ABSTRACT:
An ignition device for an internal combustion engine has a primary and secondary coils of an ignition coil, a center and ground electrodes of a spark plug, a cylinder shaped insulator and a cylinder shaped tube. The center electrode is disposed apart from the secondary coil in a longitudinal direction of the ignition device. The insulator is made of an insulating material and has a coil surrounding portion surrounding the secondary coil and a plug surrounding portion surrounding the center electrode. The primary coil is wound on an outer circumferential face of the coil surrounding portion. The ground electrode is disposed on an outer circumferential face of the plug surrounding portion. The tube is made of a magnetic material and has a coil covering portion covering the primary coil and a plug covering portion covering the plug surrounding portion and the ground electrode.
