ABSTRACT:
A coil winding structure of a flyback transformer comprises a plurality of layers of a coiled-circuit pattern sheet. The coiled-circuit pattern sheet includes a tubular sheet, a coiled-circuit pattern formed around the tubular sheet, and a magnetizable core inserted into the tubular sheet. The coiled-circuit pattern sheet and the magnetizable core have a shape of an elongated flexible strip. The coiled-circuit patterns are electrically connected in series with each other, and the magnetizable cores are connected with each other by a conductive binder and so on, so as to form a closed circuit in a zig-zag formation.
