Abstract
To reduce pattern resistance including a secondary winding in a power supply module having a pair of secondary windings transformer-coupled with a primary winding. The pair of secondary windings coupled with a primary winding through a transformer is drawn out in both directions each other, and further disposed on different layers. Also, output pattern films are disposed on both sides of the second and third layers, so that pattern films of wide shape can be produced.
