<p>PURPOSE: To provide an ignition coil for an internal combustion engine which is easily manufactured in a small size while maintaining predetermined ignition performance by forming a suitable core structure for a simultaneous ignition ignition coil. CONSTITUTION: A magnetic path is formed of an inner core and an outer core wound with a primary coil 12 and a secondary coil 22 in parallel with two sets of ignition coils 1A, 1B, and high voltage terminals are connected to the coil 22. The inner cores 2 of the two sets of the coils 1A, 1B are coaxially disposed, and an air gap 5 of a predetermined gap is formed between the outer cores 2 of the side at least opposed with the cores 2.</p> |
