PURPOSE: A focus pack structure of a flyback transformer is provided to reduce a fabrication cost and remove a badness cause by eliminating soft epoxy inserted in a focus pack case. CONSTITUTION: A focus input terminal(16) and a focus ground terminal are welded to a circuit substrate(11). An insulation wall(30) having a protruded rib(30a) is formed at a flyback case of a flyback transformer so that an empty space(P) may be formed between the insulation wall and the circuit substrate. A focus pack joining part(4) is formed at an outer side of the insulation wall so that the case(3) may be joined to the focus pack case(6). A section space is formed between a focus voltage circuit and a screen voltage circuit. A conduction-robber fixing part(30b) is integrated at one side of the focus pack case(6), and another conduction-robber fixing part is integrated at the other side of the focus pack case(6).
