ABSTRACT:
A flyback transformer has a winding portion. The winding portion includes a low-voltage bobbin, a high-voltage bobbin, low-voltage winding, and high-voltage winding, each of which having a flattened substantially circular cross-section. The high-voltage winding is wound so as to have a film-layer winding structure. Diodes are provided such that each diode is coupled between two corresponding winding elements provided in the layers. A high-voltage capacitor and a high-voltage resistance substrate are connected to the output of the high-voltage winding. The diodes, the high-voltage capacitor, and the high-voltage resistance substrate are arranged in the longitudinal direction of the flattened substantially circular cross-section of the winding portion.
