Claims

[Scope of utility model registration request]

A low-voltage bobbin with at least a primary coil wound thereon, a high-voltage bobbin with a secondary coil wound thereon, and a focus block are built into the insulation case, and a focus block with a focus volume and a screen volume is built into the outer periphery of the insulation case. A flyback transformer in which a medium-high voltage capacitor is connected between the focus terminal and the screen terminal of a focus block, and the coil portion and medium-high voltage capacitor are insulated by an insulating material filled in the insulating case.
