A flexible coil winding structure of a flyback transformer is disclosed, which comprises a magnetizable core at the center portion, a pair of flexible insulator sheets at both sides of the magnetizable core for insulating it, and first and second conductor line patterns arranged so that they can provide a coiled circuit pattern around the pair of flexible insulator sheets. The first and second conductor line patterns include respectively a plurality of first and second parallel conductor lines which are inclined at a predetermined angle. Also, the coil winding structure includes an opening, such as an etched hole or a window, etc., at a portion of the insulator sheet which corresponds to the upper and lower portions of all the conductor lines and an electrical connection for connecting through the opening the upper portions and the lower portions of the first and second conductor line patterns so that the conductor lines provide the coiled circuit pattern. The electrical connection is provided by soldering. A manufacturing process of the flexible coil winding structure is also disclosed.
