ABSTRACT:
A sheet transformer wherein a coil pattern is formed on each of substrates so as to constitute a coil substrate, a plurality of the coil substrates are overlaid in multiple layers to form a primary coil and a secondary coil. The primary coil and the secondary coil are overlaid such that the middle leg cores of EE type, EI type, EER type or EIR type cores are disposed in the center of the coils and both the outside leg cores are disposed outside the coils, thereby obtaining a magnetic coupling between the coils. A higher potential side of the primary coil and a higher potential side of the secondary coil are disposed in an opposed configuration so as to face each other.
