<p>PROBLEM TO BE SOLVED: To provide an ignition coil which can prevent leak short-circuiting of a high voltage to each part even if the core is thinned for realizing compactness. SOLUTION: In an ignition coil for an internal combustion engine provided with a secondary coil 22 consisting of a secondary wiring wound on a secondary core 23, a primary coil 21 consisting of a primary wiring wound on a primary bobbin, a central core 23 which transmits magnetic flux induced in the primary coil 21 and a central core 23 in a central core insertion part forming the primary coil 21 or the secondary coil 22, an electrical insulation sheet 70 is provided between a primary core 211 and a primary wiring, and an electrical insulation sheet 70 is provided between the central core 23 and the primary coil 21 or the secondary coil 22.</p> |
