<p>PROBLEM TO BE SOLVED: To provide a low-profile transformer that has less inductance leak, is small in height, and is high in work efficiency in a production process. SOLUTION: The low-profile transformer has a primary main winding 1 formed of a spiral coil, wound continuously in a double layer and a secondary main winding 6 sandwiched between the first layer and the second layer of the primary main winding 1. The primary main winding 1 is shifted from the first layer to the second layer on the side facing a lead wire; and the secondary main winding 6 has an opening 16 on the side opposed to the lead wire of the primary main winding 1 and is shifted from the first layer of the primary main winding 1 to the second layer.</p> |
