<p>PROBLEM TO BE SOLVED: To provide an ignition transformer, wherein inductance is not rapidly decreased even when a large current is made to flow, DC superposition characteristic is proper, and electric characteristics are improved. SOLUTION: A first magnet 21 of samarium cobalt is arranged on one end of a magnet core 18. The direction of magnetic flux in the magnetic core 18, which is generated from the first magnet 21 and the direction of magnetic flux in the magnetic core 18 which is generated from a first winding 16, are reversed with each other. A second magnet 22 of samarium cobalt is arranged on the other end of the magnetic core 18. The direction of magnetic flux in the magnetic core 18, which is generated from the second magnet 22 and the direction of magnetic flux in the magnetic core 18 which is generated from the first winding 16, are mutually reversed.</p> |
